This one is divided into industrial fixed carbon monoxide gas detector and portable carbon monoxide gas detector, I don't know what you have to ask.
-
Carbon monoxide detectors cannot detect natural gas.
Because the carbon monoxide detector is a single gas detection instrument, it can only detect the carbon monoxide gas leakage concentration alone, mainly because the working principle and the gas sensor used is the carbon monoxide sensor, which can only detect carbon monoxide, not natural gas.
If you need to test natural gas, you can use a natural gas detector, and the use of such a professional single gas detection instrument can effectively detect different gas leakage concentrations.
Since the detection of carbon monoxide and natural gas are two gases, and the gas detector is a single gas detection, two gas detectors are required. In order to facilitate the provision of multi-functional gas detectors, Coric can meet the requirements of simultaneous detection of carbon monoxide and natural gas leakage concentrations, thereby improving the work efficiency of workers.

There are two types of gas detectors: fixed gas (carbon monoxide) detectors and portable gas (carbon monoxide) detectors.
The key component of a gas detector is the gas sensor. Gas sensors can be divided into three categories in principle: a. Gas sensors that use physical and chemical properties:
Such as semiconductor type (surface control type, volume control type, surface potential type), catalytic combustion type, solid thermal conductivity type, etc.
b. Gas sensors using physical properties: such as thermal conduction, optical interference, infrared absorption, etc.
c. Gas sensors using electrochemical properties: such as constant potential electrolysis, Galvani battery type, separator ion electrode type, fixed electrolyte type, etc.
The fixed gas (carbon monoxide) detector is mainly composed of a carbon monoxide sensor and a pre-amplification circuit, and is wall-mounted, which can detect the carbon monoxide gas leakage in the environment in real time, and when the carbon monoxide gas leaks, the gas (carbon monoxide) detector outputs a 4-20mA analog signal, and the alarm controller sends out an audible and visual alarm to prompt the staff to take corresponding measures. Fixed gas (carbon monoxide) detectors are widely used in petroleum, chemical, metallurgy, electric power, coal mines, water plants and other environments to effectively prevent the occurrence of poisoning, ** and other accidents.
A portable gas (carbon monoxide) detector is an instrument that can continuously measure the concentration of carbon monoxide in the working environment. The gas (carbon monoxide) detector detects the gas concentration by natural diffusion, and adopts imported electrochemical sensor, which has excellent sensitivity and excellent repeatability; The gas (carbon monoxide) detector adopts embedded micro-control technology, simple menu operation, complete functions, high reliability, and the performance of the whole machine is at the leading level in China. The shell of the detector is refined from high-strength engineering materials and composite elastic rubber materials, with high strength and good hand feel.

The carbon monoxide detector is a single gas detection instrument, which can only detect the carbon monoxide gas leakage concentration alone, mainly because the working principle and the gas sensor used is the carbon monoxide sensor, which can only be used to detect carbon monoxide, not natural gas. Carbon monoxide and natural gas belong to two kinds of gases, and the gas detector is a single gas to detect that the main component of natural gas is methane, and a methane gas detector is required.
However, the composition of natural gas is generally methane, but if the combustion of natural gas is not sufficient, the volatile gas is carbon monoxide, so the carbon monoxide detector can detect the gas concentration after natural gas combustion.

The main component of natural gas is methane, and a methane gas detector is required.
-
Carbon monoxide detector, whether it can detect natural gas.
The composition of natural gas is generally methane. However, if the combustion of natural gas is not sufficient, the volatile gas is carbon monoxide, so the carbon monoxide detector can detect the gas concentration after natural gas combustion.
-
Carbon monoxide detectors cannot detect flammable gases.
Because the carbon monoxide detector is a single gas detection instrument, it can only detect the carbon monoxide gas leakage concentration alone, mainly because the working principle and the gas sensor used is the carbon monoxide sensor, which can only detect carbon monoxide, not natural gas.
If you need to detect flammability, you can use a combustible gas detector, and only by using such a professional single gas detection instrument can you effectively detect different gas leakage concentrations.
Because between the two, the lower limit of combustible gas is lel, and the gas concentration of carbon monoxide detection is ppm, so carbon monoxide cannot be used to detect combustible gas.
-
Combustible gas detector, an instrument capable of detecting combustible gas.
-
Probably not.
There are many kinds of combustible gases, such as hydrogen, carbon monoxide, methane, ethane, butane, natural gas, ethylene, etc., carbon monoxide is just one of them, if there are other gases in the environment that need to be detected, then the carbon monoxide detector is not applicable. Therefore, it still depends on what gas is detected, and it is better to choose a special gas detector, which can be consulted by professionals.

1. Scope of application.
This standard applies to the determination of carbon monoxide in air quality.
The assay range is 0 and the lowest detected concentration is.
2 Principle
The sample gas enters the instrument and absorbs the infrared radiation energy in the center of the spectral line in the preabsorbent membrane.
After absorbing the micro-absorption of other radiant energy. The two chambers absorb different amounts of energy. The original absorption of indoor gas is heated to produce a pressure pulse of the same amplitude, and the change of the turn force pulse is added to the differential membrane microphone through a capillary.
This is converted into a change in capacitance, which is then converted by an amplifier into a DC measurement proportional to the concentration.
3. Instruments. Carbon monoxide infrared analyzer: 0 m
Recording instrument: 0 10mV.
Flow meter: 0 10 l min.
Gas pockets, water stops, double balls.
Nitrogen: Requires that the carbon monoxide concentration is known. Or prepare a hogarat heating tube to remove the carbon monoxide.
Carbon monoxide gassing. It should be selected in the range of 60% to 80% of the instrument's range.
4. Sampling. On-site monitoring of the sample gas is used to pass the sample gas directly into the instrument inlet port.
During the on-site sampling laboratory analysis, the sample gas is squeezed into the sampling air bag with a double ball, and after emptying, it is squeezed in, so that it is cleaned 3 or 4 times, and finally squeezed and clamped the air inlet with a water stop clamp, and the sampling location, sampling date and time, and the gas collection belt number are recorded.

The ** of carbon monoxide detector is about one or two thousand yuan per unit, the cheap ones are hundreds of yuan, and the expensive ones are thousands of yuan. The carbon monoxide detector is affected by many aspects, such as brand, category, specification, market, etc. Before choosing to buy, it is necessary to understand and compare in many aspects. >>>More
What is Carbon Monoxide? Parse.
No. Carbon monoxide molecules are small and not easily adsorbed; Carbon monoxide is insoluble in water and is not a salt (does not react with acids or alkalis), making it difficult to absorb.
It is necessary to make a sealed explosion-proof fan.
