The VOC gas detector shows the cause of the error and the solution?

　　The VOC gas detector shows the cause of the greater error and the solution? The VOC gas detector, as a precision instrument for the detection of gas concentration values in the air environment, determines the quality and price of the equipment directly by the accuracy of the field gas concentration detection. What if the applied VOC gas detector shows a high degree of error?

　　The longer the gas detection alarm sensors are in use, the more frequent the gases are detected in the environment, or the detector works in a high temperature, high humidity environment, the more linear the sensor decays, which leads to increased oscillometric errors. The handling of such malfunctions requires the calibration of the standard gas in accordance with the requirements of the manufacturer ' s instructions and, if the calibration display does not reach the standard gas concentration, the sensor is judged to be ineffective and new sensors need to be replaced.

　　If there is a slow or non-reactive reaction after the inflow of the gas, the first check is whether the vents of the sensor component are blocked, and the vents of the detector are blocked or filled with impurities, thereby slowing the reaction of the hydrogen sulfide VOC gas detector and reducing sensitivity. In the absence of congestion, the fault analysis is due to the ageing or failure of the internal sensor of the detector, which requires the replacement of the sensor.

　　Therefore, in order to ensure the accuracy of the VOC gas detectors used, the user department should regularly send the sensors to the specialized department for calibration to ensure that the VOC gas detectors used in the field accurately capture the concentrations of gases in the air environment and avoid the occurrence of toxic and harmful gas leaks.
