HIGHLIGHTS
Technical Principle
Utilizes TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology for non-contact measurement.
Accuracy & Stability
Error: ±0.3% VOL at normal temperature and pressure; ±1% VOL across all operating conditions.
Concentration drift: Only 2000 ppm (over 24 hours)
Humidity: 0% to 98% RH.
Pressure: 80 kPa to 116 kPa.
Suitable for harsh environments, including high temperature and high humidity.、
Power Consumption & Integration
Operating voltage: 3.3V to 5.0V.
Average current: 40 mA.
Communication: TTL serial port.
Advantages
Resistant to cross-interference (no response to non-oxygen gases).
Long service life (stable optical system).
