How to operate a four in one gas detector
In response to the needs of environmental protection work, gas detectors in the market are becoming increasingly diverse. One of them is the four in one gas detector, which can simultaneously detect oxygen, hydrogen sulfide, carbon monoxide, and combustible gases. It has important applications in agriculture, chemical industry, construction, electricity, fire protection, natural gas, steel industry, petroleum and petrochemical, sewage treatment, and other fields. So how to use a four in one gas detector?
Usage of the four in one gas detector:
1. Before entering the work area, a safety confirmation must be conducted; Only after confirming that there are no safety hazards can one enter the working face for testing. When the detection instrument alarms, the working face should be promptly withdrawn and forced ventilation should be maintained for more than half an hour before testing. The testing personnel must write the testing results of the work site on the confirmation form and take full responsibility for the accuracy of the testing data.
2. After testing, confirm the flipping of the warning sign according to regulations. Warning signs should be hung at a reliable location at the entrance of the work site. Other personnel are not allowed to flip the warning signs and avoid being affected by other reasons; Staff are allowed to enter the work site only when they see the green surface. The on duty production supervisor shall supervise and inspect the work of the on duty inspection personnel to ensure the effective implementation of this regulation.
3. Place the probe in the environment to be tested. When there is a leakage of the measured gas, the concentration display value will increase. When the alarm setting value is exceeded, the alarm indicator light will light up and an alarm sound will sound. When the probe moves to the leakage source, the concentration display screen of the four in one gas detector will display numerical values.
4. How to use a four in one gas detector? When the battery level of the four in one gas detector is low, it indicates that the battery is almost dead. The power should be turned off in a timely manner and the battery should be charged with a charger for 10-14 hours each time!
5. Charging method: Insert the power charger into the AC220V power socket, then plug the charging plug into the charging socket of the detector, and turn on the power switch of the four in one gas detector to charge the detector. The green work light will be on, the battery light will flash, and the display screen will display. After charging is completed, turn off the power switch and unplug the charger.
6. When testing, it is necessary to maintain a minimum number of two people, one to operate and the other to monitor. A certain distance should be maintained between the front and back, and single person operation is strictly prohibited. When using a four in one gas detector, it is necessary to comply with the detection requirements, perform gas detection work diligently, and remember the detection system, detection methods, and control standards.
