six-in-one gas detector is the 1 gas detector that can detect composite gases (carbon monoxide CO, hydrogen sulfide H2S, oxygen O2, combustible gas Ex, carbon dioxide CO2, nitrogen oxide NOX) and other gases. moreover, it can also detect the concentration and temperature and humidity of any 6 gases, which can be extended to 8 gases, depending on the sensor and the on-site environment. therefore, it is very suitable for occasions that require mobile fast and accurate detection of the concentration and temperature and humidity of various gases on site and alarm over the standard. So do you know what are the precautions for using six-in-one gas detector ? The following is a brief introduction by yi yun Tian:

six-in-one gas detector use precautions:

1. Note daily calibration and testing

The six-in-one gas detector is the same as other analysis and testing instruments, it uses zero gas and a standard concentration of gas to calibrate the instrument, and the standard curve is stored in the instrument.In the measurement process, the electrical signal generated by the gas concentration to be measured is compared with the electrical signal of the standard concentration, and the accurate gas concentration value is calculated. Therefore, it is necessary to calibrate the instrument at all times and periodically.

2. Note that different sensors are interpreted at the same time.

Generally speaking, each sensor corresponds to a specific detection gas, but no gas detector can. Therefore, when choosing a gas sensor, you should try to understand the interference of other gases to the sensor to ensure accurate detection of specific gases.

3. Pay attention to the service life of various sensors

gas sensors have a certain service life, generally speaking, in portable instruments, the service life of the sensor is longer, which can be used for about 3 years; the life of the photoionization detector is four years or more; the life of the electrochemical gas sensor is relatively short, generally one to two Years; the life of the oxygen sensor is very short, about one year. Therefore, it is necessary to detect the sensor at any time and use it during the validity period of the sensor.

4. Pay attention to the concentration measurement range of the testing instrument

the six-in-one gas detector has a fixed detection range, only after the measurement is completed within the measurement range, the instrument can measure correctly, but if the measurement range is exceeded for a long time, the sensor may be damaged.

To sum up, it is the precautions for the use of the six-in-one gas detector.The six-in-one gas detector can detect gas concentrations in pipelines or confined spaces and atmospheric environments, and can also detect gas leaks. There are more than 500 types of detected gases, and it can also detect various background gases that are nitrogen or oxygen. High concentration single gas purity. In order to ensure safety, we should choose the appropriate gas detector according to the specific use environment and required functions. Only by choosing the right gas detection instrument, can we really get twice the result with half the effort and take preventive measures.
