Principle
The Portable ammonia gas detector uses the pump-suction Sampling method, and the environment gas is sucked into the instrument through the built-in micro-sampling pump. The gas is in contact with the Electrochemical sensor at the core of the instrument, and the Sensor generates a corresponding electrical signal according to the ammonia concentration. The signal is amplified and processed by a High Accuracy cryogenic bleaching amplifier and a stable power processing circuit, and then analyzed and calculated by the EFM ultra-low power 32-bit ARM processor. Finally, the ammonia concentration value is displayed on the screen in real time, 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 and safety
Standards
Explosion-proof certification: Exia ⅱ CT4
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 level as needed.
4. Detection: Extend the sampling tube into the area to be tested, and the instrument screen will display the ammonia concentration value in real time.
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 settings: Regularly perform zero-point calibration or multi-point calibration through the menu, and can self-program to set alarm parameters and other functions.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Do not use the instrument under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
* Explosion-proof level of the instrument is Exia II CT4, please use it in the specified explosion-proof area.
* Avoid strong impact or drop of the instrument to prevent damage to the Sensor and internal circuits.
* Regularly calibrate the Sensor to ensure detection accuracy, and the instrument has a calibration expiration prompt function.
* After use or when not in use for a long time, please store the instrument in a drying and cool place (storage temperature -30~ 70 ° C).
* The instrument has a built-in sampling pump, please ensure that the sampling pipeline is smooth to avoid blockage affecting the detection.
When performing operations such as data export, please ensure that the USB connection is stable.
* Do not disassemble or modify the instrument yourself, so as not to affect the performance or cause safety hazards.
