Principle
The detector uses a pump-suction Sampling method, and the environment gas is sucked into the detection gas path by a built-in micro-sampling pump. The gas is contacted with the built-in imported infrared NDIR Sensor. The Sensor is based on the principle of non-dispersed infrared to accurately determine the concentration of sulfur hexafluoride gas by detecting the absorption of specific wavelengths of infrared light. The detection signal is processed by a power circuit amplified and stabilized by a High Accuracy cryogenic drift amplifier. It is calculated by a 32-bit ARM processor, compensated for by temperature and pressure. Finally, the concentration value is displayed on the screen in real time, and an alarm is triggered when the standard is exceeded.
Applications
Sulfur hexafluoride gas leak detection, power equipment maintenance, confined space operation safety monitoring, environment monitoring, industrial safety inspection
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will warm up for about 30 seconds.
2. Select detection mode: Select normal detection mode or patrol mode through the menu.
3. Set the sampling pump gear: according to the detection needs, select the low, medium or high Sampling flow rate.
4. Detection: The sampling tube is inserted into the area to be measured, and the instrument automatically samples and displays the real-time concentration.
5. View data: You can view real-time data, historical data, STEL, TWA values, and trend graphs through the menu.
6. Data export: Connect to the computer through the USB interface to export the stored test data.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Please use it within the valid period of instrument calibration, and perform zero and multi-point calibration regularly.
* Avoid working in extreme temperatures (below -30 ° C or above 50 ° C) or Humidity (condensing environment) for long periods of time.
The instrument has an automatic fault prompt function, and should be dealt with in time when prompted.
* The sampling tube should be kept unobstructed to avoid clogging affecting the test results.
* The instrument is designed to be explosion-proof, but should not be disassembled or repaired in hazardous locations beyond the Explosion-proof level.
* When charging or data transmission, please ensure that the environment is safe and away from the detection gas.
* When not in use for a long time, please shut down and store in a drying environment.
