7. Passed the explosion-proof qualification certification, the explosion-proof level is Exia II CT4, and the shell is designed with a two-color mold that is non-slip, waterproof, dustproof and explosion-proof.
8. With self-calibration, zero-point calibration, multi-point calibration functions, and with temperature and pressure compensation.
9. Support one key to restore factory settings, gas concentration unit can be switched, with self-programming alarm parameters, STEL and TWA functions.
10. Provide the usual detection and patrol two detection modes, automatically prompt instrument failure, Sensor calibration expiration and failure.
Principle
The detector uses a pump-suction Sampling method, and the environment gas is sucked into the instrument through a built-in micro-sampling pump. The gas is in contact with the built-in imported Electrochemical sensor, and the Sensor generates an electrical signal proportional to the ammonia concentration. After the signal is amplified by a High Accuracy, Low Temperature Drift amplifier and a stable power processing circuit, it is analyzed and calculated by a 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
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. View data: You can view real-time values, MAX Maximum, STEL, TWA and other data through the screen, or export historical data through the USB interface.
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
• Before use, please ensure that the instrument is fully charged and used within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
• Avoid long-term use in environments containing silicon, lead, sulfur, phosphorus, etc., to prevent Sensor poisoning or performance degradation.
• The instrument is designed to be explosion-proof, but the battery must not be removed or replaced in hazardous locations beyond the explosion-proof level.
• Regularly calibrate the instrument to ensure detection accuracy, and the calibrating cycle is recommended to be no more than 6 months.
• When sampling, ensure that the sampling pipeline is clear and free of blockage or severe bending.
• The built-in Sensor of the instrument has a lifespan of about 3 years and needs to be replaced in time when it expires or expires.
• When cleaning the instrument, please use a soft damp cloth to wipe the shell, do not use corrosion chemical solvents or direct soaking.
• When not in use for a long time, please turn off the instrument and store it in a drying and cool (-30~ 70 ° C) environment.
