Steps to follow when using a gas detector
Step 1: Check the gas detector
When we prepare to enter the testing site using a gas detector, we must perform corresponding tests on the gas detector. What needs to be tested is whether the gas detector can work properly, such as whether the sensor is normal, whether the battery is sufficient, and whether various alarm functions are normal. These are all necessary items to be tested. However, many instruments now come with detection functions, and they will self check when turned on, such as BW solo detectors or Mesian detectors, etc.
Step 2: Determine the location of the testing site
Before using a gas detector to enter the site, we need to determine the situation. If there is a possibility of gas leakage and the gas we need to detect, we need to take corresponding protective measures in advance based on various gases. If it is toxic gas, we need to take protective measures, such as air respirators, gas masks, etc.
Step 3: Start testing
After entering the testing site, we detect the gases that need to be detected in the environment. We place the portable gas detector probe in the test environment. When there is a gas leak, the concentration displayed will increase. When it exceeds the alarm set value, the alarm indicator light will light up and an alarm sound will be emitted. When the probe moves to the leakage source, the concentration display screen of the gas detector increases and the reading is recorded.
Step 4: Testing completed
After completing various tests in the environment, we need to transmit the test data for later research and management. Some gas detectors can directly transmit the test data to electronic products such as computers through Bluetooth and wireless transmission. After data transmission, the gas detector can be turned off.
Step 5: Charging
When the gas detector is low in power, we cannot use it for detection, and the gas detector will emit a low battery alarm signal. This requires us to turn off the power and use a charger to charge the battery, which takes about 10-14 hours each time! After being fully charged, it can be used again. However, some 2-year maintenance free gas detectors, such as the Delge PAC6000 gas detector or the Mesan Tianying maintenance free gas detector, do not require battery replacement during the 2-year usage period.
Step 6: Maintenance and calibration
After using the gas detector, we should regularly clean and maintain it. After using it for six months or a year, we should calibrate the gas detector. Calibration is to ensure that the gas detector has no detection errors, so it is necessary to calibrate it regularly.
