How to Use the Gas Test Gauge?

1. Before entering the working area, safety confirmation must be carried out. After doing the corresponding safety protection, such as face masks, gas masks, etc. (see the specific scene of use). Make sure to ensure the safety of testers and prevent potential safety hazards before entering the working surface. detection. When the four-in-one gas detection instrument alarms, the working surface should be withdrawn in time, and the test data should be saved and recorded. After more than half an hour of forced ventilation, two more measurement tests should be carried out. The testing personnel must write the test results of the work site on the confirmation sheet, and take full responsibility for the accuracy of the test data.

2. After the inspection, confirm the overturned warning sign according to the regulations. The warning signs should be hung in a reliable place at the entrance of the worksite, other personnel should not flip the warning signs, and at the same time avoid being affected by other reasons; the staff are allowed to enter the work site when they see the green side.

3. Place the probe of the portable gas detector in the environment to be tested. When there is leakage of the gas to be tested, the value displayed by the concentration will become larger. When the alarm setting value is exceeded, the alarm indicator light will be on, and an alarm will sound at the same time. When the probe moves to the leak source, the value displayed on the gas detector concentration display increases, and the reading is recorded.

4. When the battery of the portable gas detector is low, it means that the battery is almost dead. You should turn off the power in time and use the charger to charge the battery!

5. Charging method: plug the power charger into the power socket, then insert the charging plug into the charging socket of the detector, and then turn on the power switch of the four-in-one gas detector to charge the detector, the green working light is on, the battery The light flashes, the display shows '----', after charging is completed, turn off the power switch and unplug the charger

The above is the answer to the correct use of the gas detector. It is worth noting that when testing personnel, there should be two or more people, one person to operate, the other to monitor, keep a certain distance before and after, and it is strictly forbidden to work alone. . The use of hand-held portable gas detectors must comply with the detection requirements, do a good job of gas detection with due diligence, and keep in mind the detection system, detection methods and control standards.
