Arrow Optoelectronics' products still have advantages in these aspects. If there's anything you don't understand, ask me.

Uncooled thermal imaging sensors operate at ambient temperatures. The cooling sensors are packaged in a single unit, keeping them at extremely low temperatures. These systems are very sensitive, which are cooled by cryogenics.

However, they are more expensive than uncooled sensors, mainly due to the complex cooling system they require.

Generally speaking, most of the thermal imaging cameras used in civilian use of uncooled sensors. However, only a few companies in China can produce refrigerated sensors.

The main difference between these two is the volume, the refrigerated ones will be much larger than the uncooled ones, and the uncooled ones can already reach the size of a coin. Although the uncooled imaging is stable, but the life is relatively short, the uncooled infrared thermal imager because of its small size, long life, low and other advantages in the rapid development of the civil industry, among which Arrow Optoelectronics, as a research and development of infrared chip enterprises, is also to uncooled infrared focal plane detector quickly occupy the market.

Compared with common cooled thermal imaging cameras, uncooled thermal imaging cameras have more advantages in terms of service life, volume, power consumption and power consumption, and the range of use is also more extensive, which we will explain one by one below.

First, the service life.

The operating time of the cooler is directly related to the service life of the thermal imaging camera, which is relatively longer in life, but the measurement accuracy will also be reduced due to the aging of the components.

2.**。In general, cooled thermal imaging cameras** are expensive, while uncooled thermal imaging cameras** are relatively low.

3.Volume. Because cooled thermal imaging cameras require the refrigerator to work together, cooled thermal imaging cameras are larger than uncooled thermal imaging cameras.

5.Sensitivity, accuracy, error.

There are many brands of infrared thermal imaging cameras, when choosing infrared thermal imaging cameras, it is recommended to choose large brands of infrared thermal imaging cameras, such as domestic Arrow Optoelectronics, foreign fluke; You can also choose according to the sales ranking of previous years, and choose the model that suits you.

All devices have anti-electromagnetic interference capabilities, you can refer to the electromagnetic interference parameters in the product. In the infrared thermal imager, the anti-interference ability of Arrow Optoelectronics is relatively good, and now you can enjoy a limited-time exchange discount, which can be worth 200 yuan.

According to the product quality and the strength of the manufacturer, it is recommended that you choose Shanghai Thermal Technology Co., Ltd., whose brand "Fotric Fei Jie Ke".

Arrow Optoelectronics' infrared thermal imager is good, such as Tianshu C200 is a vanadium oxide uncooled infrared focal plane detector, and the anti-interference ability is very good.

It's good, I've been using Arrow's thermal imaging camera for almost two years, and the accuracy has been very high, and the battery life is long, so I don't have to recharge it often. Did my answer help you? If yes,

Arrow Optoelectronics' thermal imaging system products are still very reliable, but the product is a little expensive, but you get what you pay for.

I have been using the Arrow Optoelectronics brand infrared thermal imager,There are many functions,High and low temperature three-point temperature measurement、LED light alarm prompt、Image alarm prompt,I think the best one is the offline temperature measurement and analysis function on the computer side,You can generate an effect report with one click.。。 If you don't understand, feel free to ask.

Infrared detector chips are to infrared thermal imaging cameras what CPUs are to computers. The development trend of chips is the shrinking of pixel spacing and the gradual increase of area array size. The size of the detector area array is an important indicator to judge the quality of the infrared thermal imager, and the relatively high-end product pixels in the civil infrared thermal imager are 640 512 384 288, and the infrared thermal map is clear and delicate.

In addition to area array size, cell spacing is also an important indicator. At present, the mainstream product of uncooled infrared detector chips has a pixel spacing of 12 microns. The smaller pixel spacing brings a more optimized optical system, lower power consumption, and a higher level of technology for the product.

Arrow is a domestic enterprise that has mastered the core technology of infrared detector chips, and has mastered 10 micron and even 8 micron infrared detector chip technology.

netd is the noise equivalent temperature difference, and the lower the value, the clearer the image. Poor sensitivity, the observation point is overwhelmed by noise, "invisible", resulting in the inability to ensure the most basic safety functions in the field.

Frame rate refers to the number of images processed by the camera in 1 second. The faster the sensor, the higher the internal circuit processing rate and the higher the frame rate. Thermal imaging cameras with high frame rates are suitable for capturing high-speed movement of objects.

A good thermal imaging camera should have a frame rate of 25Hz to 50Hz, otherwise it will not work in many situations. The frame rate directly indicates the performance and response speed of the thermal imaging camera. ”

Then you can take a look at the lens, spatial resolution, field of view, recognition distance and other indicators, and make a comprehensive judgment based on your specific needs. With these in mind, it's easy to pick the right thermal imaging camera brand for you.

Among the foreign brands, the German Optris brand has good performance in all aspects, and many domestic companies are using it, and the domestic CES series has superior performance, easy operation and high cost performance. Shenzhen Zhongou TEP Technology is the best supplier of German Optris and domestic CES series, and you can consult if you have needs.

Fluke in the United States is ok! It belongs to the following companies of the world's top 500 Danaher, and it is an electronic test and measurement instrument. Their thermal imaging cameras are recognized by the majority of engineers, mainly because they are durable and durable.

American brands such as RNO, Fluke, and Pyle. RNO is a high-end route, the product performance is outstanding, and the selling points of the remaining Fluke and Pyle brand thermal imagers are not prominent, ** are generally low, mainly taking the low-end route.

FLIR's infrared thermal imager in the United States is the most professional, and Fluke is also a relatively large manufacturer The product is also first-class, the disadvantage is that the high-end thermal imager has not been done, the product chain is mainly concentrated in the middle and low end, and the choice of thermal imager should be combined with your specific needs and budget to comprehensively analyze, after all, the parameters of this thing are improved a little, and the difference is tens of thousands to hundreds of thousands. The right one is the best.

Choose the brand to choose Filler and Fluke, the quality is not said, and the quality of the domestic is also very good.

rno？Chinese companies registered in the United States, hehe. Foreign Raytheon DRS FLIR, the domestic company that has mastered the chip-level core technology is the dominant in iray technology. If Lao Mei opens up barriers and sells it to China, it will have to stand aside.

The domestic infrared thermal imaging technology is also very advanced, and it is exported to many countries.

FLIR is an American brand. Thermal imagers lead the way.

RNO is a fake American product, everyone should be careful!

There are many brands of infrared thermal imaging cameras, such as FLIR, Fluke, pulsar, etc. In China, there are AutoNavi, Cottage Dali, Arrow, Bomantu, Shengli, Emma, Hikvision, etc.

Because there are too many brands, it is difficult to make comparisons, but it can only be said that within a certain range, the FLIR in the United States does work well, and the domestic Arrow effect is also very good, that is, it is more expensive than several others, and it can be considered if the economy is rich. Gaode Dalisheng is cheap, and the imaging effect is average. I haven't used it much, so I won't comment on it here.

There are several, such as Arrow, and it seems that there are also Gao De and Da Li.

Founded in 1999, Wuhan AutoNavi Infrared Co., Ltd. has been focusing on the development of infrared thermal imaging technology for 20 years, and is a high-tech listed company engaged in the research and development, production and sales of infrared core devices, infrared thermal imaging cameras and large-scale optoelectronic systems.

Let's talk about the conclusion first: foreign FLIR, Fluke, domestic: Hikvision is very competitive. The traditional ones are virtuous and vigorous.

Here's how it goes: FLIR, a leader in the manufacture of innovative imaging systems for more than 50 years, includes thermal imaging cameras, aerial cameras and mechanical inspection systems. FLIR products have played an important role in more than 60 countries around the world, including China. Along with FLIR, Fluke, which shares its American roots, is also a world leader in the production, distribution and service of electronic test tools.

Fluke entered China in 1978 at the beginning of China's reform and opening up, and has a wide range of products, including industrial test instruments, precision test instruments, network test instruments, medical test instruments and temperature test instruments.

In addition to the above two American big brothers, a number of infrared technology manufacturers have also risen in China, and today we mainly talk about AutoNavi Infrared, Dali Technology, and Hikvision. Founded in 1999, Wuhan AutoNavi Infrared Co., Ltd. is a high-tech listed company engaged in the R&D, production and sales of infrared core devices, infrared thermal imagers and large-scale optoelectronic systems. AutoNavi Infrared Industrial Park is located in "China Optics Valley", and has built a whole industry chain research and development base covering the bottom infrared core device to the top complete optoelectronic system.

Zhejiang Dali Technology Co., Ltd., formerly known as Zhejiang Testing Technology Research Institute established in 1984, completed the restructuring in 2001 and was listed on the Shenzhen ** Stock Exchange in February 2008. Dali Technology is a high-tech enterprise specializing in the development of uncooled infrared focal plane detectors, infrared thermal imaging systems, intelligent inspection robots, and inertial navigation optoelectronic products. Finally, Hikvision, the absolute amount of R&D expenses accounted for the company's sales, and the absolute amount is among the best in the industry.

And many people may not know that since 2008, Hikvision has begun to study infrared thermal imaging technology, and Hikvision's recent concept of "thousand-yuan era" is really a full range of "thousand-yuan era" products that have led from niche high-end to mass applications. According to the publicity, Hikvision's thermal imaging factory in Tonglu is manufactured and tested in strict accordance with the requirements of military quality production, and the materials are tested according to multiple standards and carefully selected; The production process is strictly controlled, the core components are fully automated, and the dust-free clean room is encapsulated; The product has undergone multiple strict tests such as aging and air tightness before leaving the factory to ensure that the product is stable and reliable.

Comparison of core parameters of the product:
