Performance requirements for carbon monoxide gas detector

carbon monoxide，The chemical formula isCO,It is a colorless, odorless, and non irritating substanceAnd highly toxicgas.It is still a gas that is easily generated,I always hear it in lifecarbon monoxideNews of poisoning and explosion leakedDue to toxic phenomena and even death, it is particularly important to accurately detect the content of carbon monoxide. This requires that the performance of carbon monoxide gas detectors must meet certain standards. So, to what extent should the performance of carbon monoxide gas detectors reach?belowEast Japan Energy EditorLet me introduce it to everyone.

1、 The measurement range of the carbon monoxide gas detector should reach01000ppm.

2、 The indication error of the carbon monoxide gas detector should be within±5umol/molscopewithInternally, the relative error should be within±10%Within the range, accurate readings can better represent the concentration of gases.

IIIThe time it takes for a carbon monoxide detector to reach a stable indicator value from the moment it comes into contact with the gas being detected under experimental conditions. Usually read to reach a stable indicator value90%The response time, abbreviated asT90.

4The drift degree of the carbon monoxide gas detector should be within the following range: zero drift should be±3umol/mol;Range drift should be ±5%.

Japan's fixed four in one gas detector（SK/MIC-600-CO2）The overall use of explosion-proof technology（d）Structure. Obtained EU certification in the domestic gas detector industryCEandROHSDual certified gas detector brand; Can be directly installed in hazardous areas1 District and2 District use; Standard configuration with backlightLCDLCD display, three wire system4~20mAsimulation andRS485Digital signal output, optional configuration includes programmable switch output and other modules, providing customized products according to user needs. It also supports output signal fine-tuning and other functions, facilitating system networking and maintenance.
