12. Support the usual detection and patrol two detection modes, with automatic cleaning gas circuit and fault prompt function.
Principle
The Portable hydrogen detector uses the pump-suction Sampling method, which draws environment gases into the instrument through a built-in micro-sampling pump. The gas contacts an imported catalytic combustion Sensor at the core of the instrument, which converts the hydrogen concentration signal into an electrical signal. The electrical signal is amplified and processed by a High Accuracy cryogenic drift amplifier and a stable power processing circuit, and finally the hydrogen concentration value is calculated and displayed by a 32-bit ARM processor. The instrument has temperature and pressure compensation to correct for the impact of environmental factors on measurement results.
Applications
Environment Monitoring, Confined Space Operation Safety Testing, Industrial Process Control, Emergency Response, Laboratory Safety
Steps
1. Turn on and warm up for about 30 seconds.
2. Select the detection mode (usually detection mode or patrol mode) as needed.
3. Set alarm parameters, STEL/TWA values, etc. through the menu (optional).
4. Place the sampling tube in the area to be tested, and the instrument inhales the gas through the built-in pump for detection.
5. Real-time reading of hydrogen concentration, MAX Maximum, STEL, TWA and other data through a 3.5-inch color screen.
6. After the test is completed, a high-grade pump can be used to clean the gas path.
7. Connect to the computer through the USB interface to download or print the stored test data.
Notice
• Please use within the valid period of instrument calibration and calibrate regularly.
• Avoid long-term operation in environments with extreme temperatures (below -30 ° C or above 50 ° C) or high Humidity (which may cause condensation).
• Pay attention to the Operating Pressure Range of the instrument (86~ 106kPa), exceeding the range may affect the Measurement accuracy.
• The instrument has explosion-proof characteristics, but it still needs to be used within the applicable area of the specified Explosion-proof level (Exia II CT4).
• After use or when not in use for a long time, it is recommended to clean the gas path.
• When performing zero or multi-point calibration, make sure to operate in a clean air or standard gas environment.
• Pay attention to the battery level to ensure that the instrument has sufficient power during the inspection process.
• Avoid strong impact or soaking of the instrument to prevent damage.
• When downloading data, please use the supporting software and follow the operation guide.
