Principle
The Portable hydrogen bromide detector works based on the principle of Electrochemical sensor. The electrolysis liquid in the Sensor undergoes oxidation and reduction reaction with the target gas (hydrogen bromide), generating an electrical signal proportional to the gas concentration. The weak signal is amplified and processed by the built-in two-stage High Accuracy low temperature drift amplifier of the instrument, and then the 32-bit ARM processor performs data operation, temperature and pressure compensation. Finally, the accurate concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard.
Applications
Environment monitoring, confined space operation safety inspection, industrial process control, emergency accident handling, occupational health protection
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 extracts air and displays real-time concentration.
5. Data viewing and export: You can view historical data through the menu, or connect to a computer through the USB interface to export data.
6. Calibration: Regularly perform zero-point calibration or multi-point calibration through the menu to ensure accuracy.
7. Alarm settings: Set the required Alarm threshold, STEL and TWA parameters through the self-programming function.
Notice
• Please read the instructions carefully before use and perform boot self-test in a safe environment.
• Instruments need to be calibrated regularly to ensure detection accuracy and avoid using expired or failed Sensors.
• Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
• Pay attention to the Operating Pressure Range of the instrument (86~ 106kpa) and avoid using it under extreme air pressure.
• The instrument is of explosion-proof design (Exia II CT4), but it is still necessary to avoid disassembly or charging in hazardous locations beyond the explosion-proof level.
• When using the sampling pump, select the appropriate gear according to the cleanliness of the environment, and use the high-grade position to clean the air path after testing.
• Avoid strong impact or immersion of the instrument in liquids to prevent damage.
• When the instrument issues a fault, Sensor expiration or low battery alarm, it should be dealt with in time.
• When not in use for a long time, please store at the recommended storage temperature (-30~ 70 ° C) and charge it regularly for maintenance.
