7. Equipped with 4000mA rechargeable polymer battery.
8. Optional range: 0 to 2000, 5000, 10000, 50000ppm.
Principle
The detector uses a pump-suction sampling method, through the built-in air pump to suck the environment gas into the inside of the instrument. After the gas passes through the dust filter, it comes into contact with the imported electrochemistry or infrared absorption gas Sensor. The Sensor generates a Response according to the specific chemical or Optical inspection characteristics of the carbon dioxide gas. Microcontroller technology processes the Sensor signal to quickly and accurately calculate the gas concentration and display it.
Applications
Gas concentration detection in various industrial environments and special environments
Standards
GB3836.1-2010、GB3836.4-2010
Steps
1. Make sure the instrument has sufficient power before turning it on.
2. According to the testing requirements, confirm or set the appropriate range and Miscellaneous parameters.
3. Place the instrument in the test environment or use the sampling Probe to align the test area.
4. Start the instrument, the built-in air pump starts to work, and the environment gas is inhaled for detection.
5. Observe the instrument display screen and read the real-time carbon dioxide concentration value.
6. After the test is completed, turn off the instrument.
7. The stored test data can be exported through the data interface.
Notice
• Do not use outside the operating Ambient Temperature (-30~ 60 ℃), Humidity (0~ 95% RH without condensation) and Air Pressure (-30~ 100Kpa) range.
• The instrument is equipped with a dust filter, and the state of the filter should be paid attention to when using it in a harsh environment, and it should be cleaned or replaced if necessary.
• Avoid strong impact or falling of the instrument.
• Please use the matching charger when charging.
• When not in use for a long time, please charge and maintain the battery regularly.
• The instrument is marked explosion-proof (CNEx16.0538), but still needs to be used in the specified explosion-proof environment and comply with relevant safety regulations.
• When calibrating or maintaining, please refer to the instructions or contact a professional.
