Principle
The Portable nitric oxide detector adopts the pump-suction Sampling method, which actively sucks the environment gas into the detection gas path through the built-in micro-sampling pump. The gas contacts the imported Electrochemical sensor inside the instrument, and the Sensor generates the corresponding electrical signal according to the concentration of nitric oxide. After the signal is amplified by two-stage High Accuracy low temperature drift amplifier and processed by a high-stability power supply processing circuit, the EFM ultra-low power 32-bit ARM processor performs data analysis and calculation, and finally the concentration value of nitric oxide is displayed in real time on the 3.5-inch full-color TFT screen. The instrument has temperature and pressure compensation functions, which can accurately compensate the gas concentration in different environments.
Applications
Environment monitoring, industrial safety, confined space operation, emergency rescue, chemical production, laboratory testing
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, set the sampling pump to low, medium or high level in the menu.
4. Detection: The sampling tube is placed in the environment to be tested, and the instrument automatically samples and displays real-time concentration.
5. Data viewing and storage: During the detection process, data is automatically stored, and historical data or trend charts can be viewed through the menu.
6. Data transfer: Connect to a computer via USB to download or print stored data.
7. Calibration and settings: Regularly perform zero-point calibration, multi-point calibration or alarm parameters and other self-programming settings through the menu.
8. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
• Please use within the range of Ambient Temperature (-30~ 50 ℃) and Humidity (10~ 95% RH without condensation) specified by the instrument.
• Avoid long-term use in strong electromagnetic interference, high concentration dust or corrosion gas environment.
• Regularly calibrate the Sensor to ensure detection accuracy, and the instrument will prompt when the Sensor calibration expires or fails.
• Before use, please check whether the sampling tube is unobstructed and whether the air passage is clean. If necessary, use the high-end position of the sampling pump for air passage cleaning.
• Instruments are designed to be explosion-proof, but must not be disassembled or repaired in hazardous locations beyond the Explosion-proof level.
• Please charge in time when the battery is low to avoid data loss due to power failure during the detection process.
• Please store in a drying and cool place to avoid high temperature and high humidity environment. The storage temperature is -30~ 70 ℃.
When downloading or charging data, make sure to use the matching USB cable and Power Adapter.
