Principle
The Portable ammonia gas detector uses a pump-suction Sampling method to actively extract environmental gases through a built-in micro-sampling pump. After the gas enters the instrument, it reacts with the internal Electrochemical sensor. The Sensor converts the ammonia concentration signal into an electrical signal, which is amplified by a High Accuracy, Low Temperature Drift amplifier and processed by a stable power supply circuit. The 32-bit ARM processor analyzes and calculates the ammonia concentration value. 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
This product is suitable for various occasions where ammonia concentration in the environment or confined space needs to be monitored.
Standards
Explosion-proof level: Exia ⅱ CT4
Steps
1. Power on and warm up (about 30 seconds).
2. Select the detection mode (usually detection mode or patrol mode) as needed.
3. Set alarm parameters, STEL/TWA and other parameters through the menu (optional).
4. Place the sampling tube in the area to be tested, and the instrument inhales the gas through the built-in pump for detection.
5. Observe the real-time concentration, MAX Maximum, STEL, TWA and other information displayed on the screen.
6. After the test is completed, a high-grade pump can be used to clean the gas path.
7. Connect to the computer through the USB interface to download or print the stored data.
Notice
* Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
* Note the Operating Pressure Range of the Instrument (86~ 106kPa).
* The instrument has explosion-proof characteristics, but still needs to be used in the specified explosion-proof environment.
* Sensor calibration is performed regularly to ensure measurement accuracy, and the instrument will prompt that the calibration has expired.
After use or when not in use for a long time, it is recommended to clean the gas path.
Avoid strong impact or immersion of the instrument in liquids.
* Please store in a drying environment with a storage temperature of -30~ 70 ° C.
* For zero or multi-point calibration, please use standard gas and operate in a safe environment.
* Pay attention to the service life of the Sensor (about 3 years), and it needs to be replaced when it expires.
