Petroleum and petrochemical, chemical plants, smelters, steel plants, coal plants, thermal power plants, scientific research, production workshops, Tobacco companies, environment monitoring, school scientific research, building construction, fire alarm, sewage treatment, industrial gas process control, boiler room, waste treatment plant, tunnel construction, oil pipeline, gas station, underground gas pipeline maintenance, indoor air mass detection, dangerous place safety protection, aerospace, military equipment monitoring
Standards
EMI, EMC Standard, National Standard Testing, CMC Measurement Equipment License Certification, GB 3836.1 - 2010, GB 3836.2 - 2010, GB 3836.4 - 2010
Steps
1. Fixed installation of the detector at the designated location.
Connect the power supply and output interface (e.g. RS485 or 4-20mA).
3. Use the infrared remote control for parameter setting, including modifying the alarm point, concentration calibrating, zero calibrating, etc.
4. Monitor the gas concentration, temperature, Humidity and other information displayed on the LCD screen.
5. Connect external devices such as alarms or Control systems as needed.
Notice
• Ensure that the Working Ambient Temperature is in the range of -30~ 50 ℃, and avoid exceeding the storage temperature of -40~ 70 ℃.
• Environmental humidity should be controlled at 0~ 95% RH non-condensation state.
• Pay attention to explosion-proof requirements during installation to avoid misuse in non-hazardous places.
• Regularly calibrate and maintain to prevent long-term drift from affecting accuracy.
• When operating with an infrared remote control, ensure that the lid-free adjustment is carried out under safe conditions.
