Body detector care and maintenance
Zhuhai Tianchuang Instrument will answer you in detail about how to maintain and maintain the gas detector after using it for a period of time:
maintainance
1. Check the gas flow rate, usually 30/h, if the flow rate is too large or too small, it will have a great impact on the analyzer results
2. Replace the filter paper: stop the air pump and drain the filter tank
3. Check whether there is any air leakage in the air system. Whether the diaphragm of the weeping pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensate are damaged, etc.
4. Clean the sampling probe and dredge the sampling hole pipeline
5. Check whether the condenser works normally, usually the temperature is adjusted within 3 degrees Celsius
6. Check the measuring chamber to see if it is dirty, and clean it in time.
maintain
1. Inspection of the whole machine: the detector should be checked regularly at ordinary times, and its signal current is DC4mA in clean air
2. Sensor maintenance: Generally, it needs to be rechecked and calibrated after installation and use for half a year to one year, and the tester will issue a test report.
3. When the sensor of the gas detector loses its sensitivity, it needs to be replaced. Through regular calibration, it will be known whether the sensor is invalid. When the calibration value does not reach the calibration gas value, the sensor should be replaced.
