6. Built-in long-life imported micro sampling pump, which can adjust the cleaning gas path through the gear.
7. Meet the explosion-proof qualification certification, and the explosion-proof level is Exia II CT4.
8. Adopt non-slip, waterproof, dustproof and explosion-proof two-color mold shell.
Principle
The detector uses a pump-suction detection method, and the environment gas is sucked into the instrument through a built-in micro-sampling pump. The gas is contacted by an imported catalytic combustion Sensor, which converts the gas concentration signal 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 finally the gas concentration value is calculated and displayed by a 32-bit ARM processor. The instrument has temperature and pressure compensation functions to adapt to accurate measurement in different environments.
Applications
Environment monitoring, confined space testing, industrial safety
Steps
1. Boot warm-up: Turn on the instrument and wait for about 30 seconds to warm up.
2. Select detection mode: Select the usual detection mode or patrol mode as needed.
3. Set the sampling gear: according to the detection environment, select the low, medium or high sampling pump speed through gear adjustment.
4. Detection: The sampling tube is placed in the area to be tested, and the instrument automatically samples and displays the real-time concentration.
5. Data viewing and export: You can view historical data, STEL, TWA values through the on-screen menu, or export data through the USB interface.
6. Calibration and setting: According to needs, use self-calibration, zero-point calibration or multi-point calibration functions to calibrate, and can set alarm parameters.
7. Cleaning the gas path: After the inspection is completed, the automatic cleaning function can be used to clean the gas path.
Notice
• Before use, please ensure that the instrument has passed the explosion-proof certification and operates in the specified explosion-proof environment.
• Avoid use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
Sensor calibration is performed regularly to ensure measurement accuracy, and attention is paid to the calibration expiration or failure information prompted by the instrument.
• When sampling, please select the appropriate pump suction gear according to the environment and ensure that the sampling tube is smooth.
• The instrument has an automatic fault prompt function. If there is a fault prompt, please deal with it in time or contact a professional.
When storing and transporting, please avoid extreme temperatures (storage temperature -30 to 70 ° C) and strong impacts.
• When exporting or setting data, please follow the menu instructions. If you make a mistake, you can use the one-click factory reset function.
• Pay attention to the service life of the instrument (about 3 years), and maintain and check it regularly.
