Principle
The Portable ammonia gas detector uses the pump-suction Sampling method, and the environment gas is sucked into the detection gas circuit through the built-in micro-sampling pump. The gas contacts the imported Electrochemical sensor inside the instrument, and the Sensor converts the ammonia concentration signal into an electrical signal. The electrical signal is amplified by a High Accuracy, Low Temperature Drift amplifier and processed by a stable power processing circuit. Finally, the EFM ultra-low power 32-bit ARM processor calculates and displays the real-time ammonia concentration value. The instrument has temperature and pressure compensation functions to correct the impact of different environmental conditions on the measurement results.
Applications
Environment monitoring, confined space operation, industrial safety, chemical production, agricultural breeding, sewage treatment, laboratory
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: adjust the sampling pump to low, medium or high grade as needed.
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. 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 and setting: zero-point calibration, multi-point calibration or setting alarm parameters through self-programming function as needed.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
• Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
• Avoid strong impacts or drops on the instrument to prevent damage to the Sensor and internal circuits.
• Regularly calibrate the instrument to ensure detection accuracy.
• The instrument has an explosion-proof design, but it is still necessary to avoid disassembly or repair in hazardous locations beyond the explosion-proof level.
• After use, it is recommended to run the high-end pump speed of the instrument to clean the air path.
• When charging or connecting the USB data cable, please ensure a safe environment and keep away from flammable and explosive gases.
• If the instrument indicates that the Sensor is faulty, the calibration is expired or invalid, it should be dealt with in time or contact a professional.
• When storing, please place in a drying and cool place to avoid extreme temperatures (storage temperature -30~ 70 ° C).
