Principle
The Portable hydrogen detector uses a pump-suction Sampling method that draws in environmental gases via a built-in micro-sampling pump. The gas comes into contact with the instrument's Electrochemical sensor, which generates an electrical signal proportional to the hydrogen concentration. The signal is amplified and processed by a High Accuracy cryogenic bleach 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 for accurate measurement in different environments.
Applications
Environment monitoring, confined space testing, industrial safety
Steps
1. Turn on and warm up for about 30 seconds.
2. Select the detection mode (usually detection mode or patrol mode) through the graphical menu.
3. Set the sampling pump gear (low, medium and high grade) as required.
4. Place the sampling tube in the area to be tested for detection.
5. Observe the real-time concentration, MAX Maximum, STEL, TWA and other data displayed on the screen.
6. Data can be downloaded or printed by connecting to a computer via the USB interface.
7. Use self-calibration, zero-point calibration or multi-point calibration functions to calibrate the instrument.
