Measurement range: 0~1000ppm (expandable to 2000ppm/3000ppm)
Response time (T90): ≤ 25 seconds
Linear error: ≤± 2% FS
Working principle: Non dispersive infrared (NDIR), dual wavelength technology, temperature compensation
Anti interference ability: not affected by gases such as H2O, alcohol, CO2, etc
Electrical Characteristics
Supply voltage: 3.3~6VDC
Drive current: average 45mA, maximum 180mA
Power consumption: average 0.23W
Output signal:
Analog output: 0.4~2V
Digital output: Modbus RTU (1200bps)
physical properties
Shell material: High temperature resistant and corrosion-resistant stainless steel
Volume: Standard 7-series structure, compact and easy to integrate
Service life: Long life (NDIR technology can reach 10 years)
Additional features
Communication protocol: Supports Modbus RTU
Pin definitions: V+/V - (power supply), Tx/Rx (serial port), OUTPUT (analog output)
Preheating time: 1 minute
Application scenarios
Suitable for SF6 leakage monitoring, purity analysis, and online monitoring systems in power equipment, which can be integrated into GIS controllers or IoT platforms. ‌
