With the needs of environmental protection work, there are more and more types of gas detectors on the market. The four-in-one detector is one of them. It can detect oxygen, hydrogen sulfide, carbon monoxide and flammable gases at the same time. It is used in agriculture, Chemical, construction, electric power, fire protection, natural gas, steel, petroleum and petrochemical, sewage treatment and other industries have important applications. Then how do we use the four-in-one gas detector? The following is Yi Yuntian Xiaobian introduction.

usage:

before the 1. enters the operation area, it must be confirmed that there is no potential safety hazard before entering the working face. After the test instrument alarms, the working surface should be removed in time, and the test should be carried out after the forced ventilation exceeds half an hour. The inspector must write the test results at the workplace on the 1 confirmation and be fully responsible for the accuracy of the test data.

After the 2. inspection is completed, confirm to turn over the warning board as required. Choose a reliable position to hang the warning board at the entrance of the operation site. Other personnel are not allowed to turn over the warning board to avoid being affected by other reasons. The staff can see green before entering the operation site. The team leader shall supervise and inspect the work of the team leader's inspectors to ensure the effective implementation of this regulation.

3. the probe is placed in the environment to be measured. When the measured gas leaks, the concentration value display value increases. When the alarm setting value is exceeded, the alarm indicator will light up and an alarm will sound. The four-in-one gas detector displays its concentration value when the probe moves to the leak source.

4. how to use the four-in-one gas tester? When the battery of the four-in-one gas detector is low, it means that the battery is close to the power-off state. Turn off the power in time and use the charger to charge the battery. The charging time is 10-14 hours each time!

5. charging method: plug the power charger into the AC220V power socket, insert the charging plug into the detector charging socket, turn on the power switch of the four-in-one gas detector to charge the detector, the green work light is on, The battery light flashes and displays. After charging, turn off the power switch and unplug the charger.

When inspecting, the inspectors should maintain more than two people, one person to operate, the other person to monitor, keep a certain distance before and after, and do not work alone. The four-in-one gas detector must comply with the testing requirements, strictly follow the testing procedures, testing methods and control standards, and do a good job in gas testing.

Regarding the use of the four-in-one gas detector, I will not repeat it here. In addition, the four-in-one gas detector should be calibrated before use. After that, it should be based on the use and exposure of the instrument to harmful gases or The degree of pollutants is regularly calibrated. Calibration is recommended every 180 days.
