Principle
The detector is based on the principle of Electrochemical sensor. The sensor converts the concentration of phosphating hydrogen gas in the environment into an electrical signal, amplifies and processes the signal through the built-in High Accuracy low temperature drift amplifier and stable power processing circuit, and finally calculates and displays the concentration value by the 32-bit ARM processor. The instrument adopts the pump-suction Sampling method, and the gas is sucked into the gas path through the built-in micro-pump to ensure fast Response and accurate measurement.
Applications
Environment monitoring, confined space operation, industrial safety, chemical production, warehousing and logistics, emergency rescue
Steps
1. Boot warm-up: Press the power button for a long time to turn it on and wait about 30 seconds for the warm-up to complete.
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, adjust the sampling pump to low, medium or high level.
4. Detection: The sampling tube is placed in the environment to be tested, and the instrument automatically displays the real-time concentration value.
5. Data viewing and export: View historical data through the menu, and use the USB interface to connect to the computer to export or print data.
6. Calibration and settings: Regular use of self-calibration, zero or multi-point calibration functions, alarm parameters, STEL/TWA, etc. can be set in the menu.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
• Before use, make sure that the instrument is fully charged and work at the Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the instructions.
• Avoid use in environments with strong electromagnetic interference, high concentrations of corrosion gases or dust to prevent damage to the Sensor.
• Sensor calibration is performed regularly to ensure measurement accuracy. If the calibration is prompted to expire or lose effect, it will be dealt with in time.
• The sampling pump has an automatic cleaning function, but it is recommended to manually clean the air passage after long-term use to prevent blockage.
• Instruments are designed to be explosion-proof, but must not be disassembled or modified in hazardous locations beyond the Explosion-proof level.
Store in a drying and cool place to avoid high temperature (over 70 ° C) or low temperature (below -30 ° C) environment.
• If there is a fault prompt, please refer to the instructions or contact a professional maintenance personnel, and do not disassemble it yourself.
When replacing the Sensor or Battery, make sure the instrument is turned off and original parts are used.
