How many instruments are suitable for automotive formaldehyde detection?

There are several instruments suitable for automotive formaldehyde detection do not know, formaldehyde test box can test formaldehyde, according to my years of construction experience, formaldehyde exceeds the standard has the following solutions:

1. Activated carbon adsorption method.

Solid activated carbon has the characteristics of many pores, has a strong adsorption and decomposition effect on formaldehyde and other harmful substances, but is easy to saturate, Ye Guangni is a new type of activated carbon, containing graphene and SOD cellulase, will not be saturated, can be adsorbed and decomposed harmful substances.

2. Ventilation method.

The practical way is to ventilate, if the natural wind is not enough, enough, you can also use an electric fan as an auxiliary tool to speed up the movement of the airflow.

3. Plant absorption method.

Plants have a strong ability to absorb, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large leaves and vanilla have a better absorption effect, such as spider plant, tiger tail orchid, etc.

I don't know much about the instruments suitable for automotive formaldehyde detection, but CCTV now reveals that the formaldehyde detection instruments sold online seem to be fake. In fact, every car has formaldehyde, but in fact, it is of little significance. Every new car should do a good job of removing formaldehyde, usually use the photophyll materials recommended by the 4S store, and ventilate frequently.

With a little greenery, formaldehyde can be removed quickly.

The better brands of formaldehyde detectors are Quanzheng Instrument, Interscan4160, Ji Swan, PPM-400ST, Taiyikang.

1. Quanzheng instrument

Quanzheng is also the first company to launch a formaldehyde detector to match the phenol reagent, which greatly increases the accuracy and stability of the detection; The Quanzheng detector is composed of imported silicon light source, square colorimetric utensils, imported sensors developed and designed by Silicon Valley, Quanzheng 3S cloud computing microprocessor, winter temperature compensation system, and built-in hyperbolic detection system, which can directly display the formaldehyde content in the measured sample.

2、interscan4160

The instrument has a battery-powered built-in sampling pump, and the detection element is a high-sensitivity, high-stability, high-accuracy electrochemical sensor, the sensor is linear and stable, and the results are accurate. The high-precision electrochemical sensor with patented technology has a short response time, continuous pumping sampling, small size, light weight, simple operation, easy to carry but high.

3. Ji swans

The swan detector is composed of a host, a sample pretreatment device and a reagent package, etc., packaged in a whole box, the instrument is small in size, light in weight, simple in operation, and suitable for use in the field and laboratory. The solid-state light-emitting device is used as both the light source and the monochromator, and the light source monochromator, the color slot, and the sensor are integrated, and there is no moving part.

4、ppm-400st

The use of imported chips, cloud computing microprocessors and special phenol reagents for the laboratory makes the instrument have the advantages of high accuracy, high stability and repeatability; In addition to accuracy, the instrument also has a very professional appearance of laboratory instruments, and the instrument also has temperature, humidity display, power display, large-capacity lithium battery to ensure battery life, and the same configuration of products is very cost-effective.

5. Taiyikang

The instrument has a built-in working curve, which does not need to configure standard solutions, and only needs to be calibrated with matching reagents for rapid quantitative determination of samples. The sample is colored and measured in the same closed vessel (cylindrical), which does not need to be transferred, improving the detection accuracy. It is simple to operate and easy to use.

Formaldehyde detector purchase skills:

1. Look at the sensor.

Formaldehyde detectors usually use electrochemical sensor method, which has been authoritatively demonstrated at home and abroad. Observe the sensor type through the air inlet of the detector. Secondly, you can consult the merchant about the type of sensor, if it is a semiconductor, you don't consider it directly, and you can't measure formaldehyde if you buy it.

Look at it again**, hundreds of formaldehyde detectors must use the principle of semiconductor detection, and they can be directly ignored.

2. Look at the accuracy.

The national standard GB T18883-2002 "Indoor Air Quality Standard", the formaldehyde concentration is accurate to two decimal places, that is, accurate, and the products of regular manufacturers are designed in strict accordance with national standards.

Lekong Formaldehyde Detector, Lekong Formaldehyde Detector LKC-200 is a new household formaldehyde concentration detection instrument.

Agrith, Prosecutor, Celestial, etc.

Take, for example, prosecutors. The inspector brand is a brand of Shanghai Aike Biotechnology, which is an enterprise that produces, develops, distributes and distributes wholesale inspector formaldehyde detectors, air detectors, formaldehyde scavengers and self-test boxes, and enjoys a high status among consumers.

The inspector has strong brand strength, credit, abiding by the contract, ensuring product quality, and has won the trust of customers with the principle of multi-variety management characteristics and small profits and quick turnover.
