10. With two detection modes of normal detection and patrol, alarm parameters, STEL and TWA functions can be set.
Principle
The 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 contacted by the built-in imported Electrochemical sensor, which converts the phosphating hydrogen (PH3) gas concentration into an electrical signal. The electrical signal is amplified and processed by a High Accuracy cryogenic drift amplifier and a stable power processing circuit, and then analyzed and calculated by the EFM ultra-low power 32-bit ARM processor. Finally, the real-time concentration value is displayed on the screen. The instrument has temperature and pressure compensation functions to achieve accurate measurement in different environments.
Applications
Environment monitoring, confined space operation safety inspection, industrial process control, storage safety, emergency rescue
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and 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, select the low, medium or high Sampling flow rate.
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 alarm parameter setting as required.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
• Please read the instructions carefully before use to ensure that it is used within the instrument range (0-20ppm) and applicable environment (temperature -30~ 50 ° C, Humidity 10~ 95% RH without condensation).
• Avoid strong impact or drop of the instrument to prevent damage to the Sensor and internal circuits.
• Sensor calibration is performed regularly to ensure detection accuracy, and the instrument will prompt that the calibration has expired.
• When used in potentially explosive environments, it is necessary to ensure that the instrument explosion protection mark (Exia II CT4) meets the field requirements.
• The sampling tube should be kept clean and open to avoid clogging affecting sampling.
• The instrument has a built-in battery, please use the matching charger when charging, and keep away from high temperature and fire sources.
• If the instrument malfunctions, alarms or abnormalities, it should be stopped immediately and a professional should be contacted for maintenance.
Store in a drying and cool place (storage temperature -30~ 70 ℃) to avoid long-term exposure to corrosion gases.
