Four factors that cannot be ignored when choosing a carbon monoxide detector:
The gas detector is small in size and easy to operate. However, in order to makegas detectorTo play a better role in use, the following four points cannot be ignored:
First, pay attention to the lifespan of various sensors:
Generally speaking, in portable instruments, the service life of LEL sensors cannot be ignored, it can be used for about three years; The lifespan of the photoionization detector is 4 years or more; The lifetime of electrochemical-specific gas sensors is generally 1 to 2 years; The life of the carbon monoxidegas detector sensor is approximately 1 year. The lifespan of an electrochemical sensor depends on how dry the electrolyte is, and if it is not used for a long time, sealing it in a low-temperature environment can extend its life. Due to the relatively large size of the fixed instrument, the service life of the sensor is also relatively long.
Secondly, pay attention to regular calibration and testing:
Toxic and harmfulgas detectorLike other analytical and testing instruments, it is determined by the relative comparison method. Therefore, it is necessary to zero the instrument at any time and calibrate the instrument regularly to ensure the accuracy of instrument measurement.
Third, pay attention to the concentration measurement range of the gas detector:
The carbon monoxidegas detector has a fixed detection range. Accurate measurements can only be made when the measurement is completed within the measurement range.
Fourth, pay attention to simultaneous interpretation interference between different sensors:
In general, eachgas detectorThe sensor corresponds to a specific detection gas. Therefore, in the selectionGas sensorWhen the sensor is interfered with, try to understand the interference of other gases on the sensor.
