At present, in the fields of agriculture, chemical industry, construction, electric power, fire protection, natural gas, steel industry, petroleum and petrochemical industry, sewage treatment and other fields, the application of four-in-one gas detector is inseparable. It can be used to detect the concentration of 4 gases such as oxygen sulfide, carbon monoxide, oxygen, combustible gas, etc., and provide vibration and sound alarms to ensure that dangerous gases can be detected in very unfavorable working environments, remind the staff to stay away from danger immediately. Therefore, in order to ensure that the four-in-one gas detector is in good working condition, we must follow the relevant precautions in the process of using it. Then four-in-one gas detector what should be paid attention to when using? The following is a brief introduction by yi yun Tian:

precautions for using four-in-one gas detector:

1. Charge the four-in-one gas detector before use. It is recommended to charge the tester after each working day.

2. The instrument should be calibrated before use. After that, it should be calibrated regularly according to the use and the exposure of the instrument to harmful gases or pollutants. It is recommended that calibration must be performed every 180 days (6 months).

3. The four-in-one gas detector can only be used in a potentially explosive gas environment with an oxygen concentration not exceeding 20.9%(v/v).

4. Check whether there is air leakage in the gas circuit system of the four-in-one gas detector. Whether the diaphragm of the sobbing pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and cold condensate are damaged, etc.

5. It is recommended to" Impact testing ", I .e. by exposing it to a gas whose concentration exceeds its high limit alarm point, confirms that the detector is able to respond to the gas and activates audible and visual alarms. Such as detector reading Outside the specified range, it should be calibrated.

6. Before entering the working section, after confirming that there are no safety problems, you must enter the working face for inspection. When the inspection equipment gives an alarm, immediately remove the operation surface and conduct the inspection after forced ventilation for more than 30 minutes. The inspector must write the inspection results of the workplace on the confirmation letter and take full responsibility for the accuracy of the inspection data.

The above introduction is the precautions for the use of the four-in-one gas detector. In the process of using the four-in-one gas detector, the detection personnel should keep the number of more than two people, one person should operate, the other person should monitor, keep a certain distance before and after, and single operation is strictly prohibited. The use of four-in-one gas detector must comply with the testing requirements, do a good job of gas testing with due diligence, and keep in mind the testing system, testing methods and control standards.
