10. It has one-click factory reset, self-programming to set alarm parameters, STEL and TWA functions, and two modes of detection and patrol.
Principle
The Portable sulfur dioxide detector uses a pump-suction Sampling method, which sucks environment gases into the instrument through a built-in micro-sampling pump. The gas comes into contact with an Electrochemical sensor at the core of the instrument, which generates a corresponding electrical signal based on the concentration of sulfur dioxide. The signal is amplified and processed by a High Accuracy cryogenic drift amplifier and a stable power processing circuit. Finally, the microprocessor based on the EFM ultra-low power 32-bit ARM calculates and converts it into a sulfur dioxide concentration value, which is displayed on the screen in real time.
Applications
Environment Monitoring, Confined Space Operation Safety Testing, Industrial Process Control, Emergency Response, 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: 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 area to be tested, and the instrument automatically samples and displays the real-time concentration value.
5. View data: You can view real-time data, historical data, STEL, TWA values, and trend graphs through the menu.
6. Data export: Connect to the computer through the USB interface to export the stored test data.
7. Calibration and setting: zero-point calibration, multi-point calibration or alarm parameter setting through self-programming function on demand.
Notice
• Please make sure that the instrument is fully charged before use and use it under the environment conditions specified in the manual (temperature -30~ 50 ℃, Humidity 10~ 95% RH without condensation).
• Avoid use in environments with strong electromagnetic interference, high concentrations of corrosion gases, or potentially explosive gases, unless the environment is confirmed to meet the Exia II CT4 Explosion-proof level requirements.
• When sampling, pay attention to the cleaning and smoothness of the sampling tube, and regularly use the pump cleaning function that comes with the instrument (by adjusting the gear) to clean the air path.
Sensors have a lifespan of about 3 years and need to be calibrated regularly to ensure accuracy. When the instrument prompts that the Sensor calibration has expired or is faulty, it should be dealt with in time.
• Data storage capacity is about 300,000 groups, pay attention to regularly export data to prevent overwriting.
• The instrument has a one-click factory reset function, but please confirm that important data has been backed up before operation, because this operation will clear user-defined settings.
• Although the instrument housing is protective, it should still avoid severe impact, immersion in water, or prolonged exposure to extreme temperatures.
Before replacing the battery or performing any repair operations, ensure that the instrument is in a safe environment and has been turned off.
