Introduction to how to use portable gas detector
When we use a gas detector to prepare for entering the testing site, we must perform corresponding tests on the gas detector. We need to check whether the gas detector can work properly, such as whether the sensor is normal, whether the power is sufficient, and whether various alarm functions are normal. These are all essential items that must be tested, but now many instruments have their own detection functions and start self checking.
Step 2: Determine the location of the testing site
Before using a gas detector to enter the site, we need to determine the situation on site. If there is a possibility of gas leakage and the gas we need to detect, we should take corresponding protective measures in advance based on various gases. If it is a toxic gas, we should 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 tested in the environment and place the portable gas detector probe in the test environment. When the tested gas leaks, the concentration display value increases. When the alarm set value is exceeded, the alarm indicator light will light up and an alarm sound will be emitted. When the probe moves to the leakage source, the value displayed on the gas detector concentration screen increases and the reading is recorded.
Step 4: Complete the detection
After the environmental inspection is completed, it is necessary to transmit the inspection data for the convenience of later research and management. Some gas detectors can directly transmit detection data to computers and other electronic products through Bluetooth and wireless transmission, and turn off the gas detector after data transmission.
Step 5: Charging
When the gas detector is low on power, we cannot use it for detection. The gas detector will emit an alarm signal indicating low power. We turn off the power and charge the battery with a charger for about 10-14 hours each time. After charging, it can continue to be used, but some 2-year maintenance free gas detectors do not require battery replacement during their 2-year service life.
Step 6: Maintenance and Calibration
After use, the gas detector should be cleaned and maintained regularly. After six months or a year of use, the gas detector should be calibrated to ensure that there is no detection error, so it is necessary to calibrate the gas detector regularly.
