The following is the general detection process of the new universe combustible gas detector:
1. Preparation work
Check battery level: Before use, ensure that the instrument has sufficient battery level for testing. If the battery level is low, it should be charged or replaced in advance to ensure the smooth progress of the detection process.
Calibration of instruments: Regularly calibrating instruments according to the manufacturer's guidelines is a key step in ensuring accurate readings. Calibration usually involves using a standard gas of known concentration for comparison and calibration, so that the instrument can accurately reflect the actual gas concentration.
Cleaning the sensor: Remove dust or other pollutants around the sensor, as these impurities may affect the sensitivity of the sensor and the accuracy of the detection results. Keeping the sensor clean helps improve the reliability of detection.
2. Startup and self check of the new universe combustible gas detector
Power on: Start the instrument according to the operating manual. Generally, press and hold the power button for a few seconds to turn it on. Different models of combustible gas detectors may have slight differences in their startup methods, but the basic principles are the same.
Self check: After the instrument is started, it will automatically run a self check program to check whether the working status of each sensor is normal. At this point, it is important to closely monitor whether the various indicator lights of the instrument are lit up properly and whether there are any error messages appearing. If everything is normal, it means the instrument is ready for testing; If there are problems, they need to be promptly investigated and resolved.
3. Set detection parameters
Select detection mode: Select the corresponding detection mode according to the type of gas that needs to be detected. For example, some models can detect multiple combustible gases, and users need to set them correctly according to the actual situation to ensure that the instrument can accurately detect the target gas in a targeted manner.
Set alarm value: Set the alarm threshold according to the safety standards of the workplace. This is to issue an alarm in a timely manner before the gas concentration reaches a dangerous level, reminding the staff to take necessary safety measures. For example, in China, for the detection of combustible gases, lower explosion limit (LEL) alarm points are generally set up.
4. New universe combustible gas detector for detection
Turn on the vacuum pump (if any): Some combustible gas detectors are equipped with a vacuum pump function. In this case, the vacuum pump needs to be turned on to extract the sample gas. By using the suction pump, the gas in the test area can be introduced into the instrument for analysis, thereby improving the accuracy and efficiency of the detection.
Reading data: During the detection process, carefully observe the readings on the instrument display screen, understand the changes in gas concentration in real time, and record the detection results in a timely manner. Some advanced models may also have data storage capabilities for easy viewing and analysis of historical data in the future.
Pay attention to alarm signals: Once the gas concentration reaches or exceeds the preset alarm threshold, the instrument will immediately emit an audible and visual alarm signal. At this point, the staff must attach great importance, quickly assess the situation on site, and take corresponding emergency measures, such as evacuating personnel, searching for the source of the leak, etc., to prevent accidents from happening.
5. Shutdown and maintenance
Shutdown: After the detection is completed, turn off the instrument in the correct order and unplug the power or remove the battery. The correct shutdown operation can protect the instrument from damage and extend its service life.
Maintenance: Regularly perform comprehensive maintenance on the instrument, including cleaning filters, checking the status of sensors, etc. Filters can block impurities from entering the interior of the instrument, but they will gradually clog over time, so they need to be cleaned or replaced regularly; At the same time, it is also necessary to regularly check whether the performance of the sensor has decreased, and if necessary, calibrate or replace it to ensure that the instrument is always in good working condition.
