Measuring Range: 0-10000 ppm
Linear Error: ±2% Full Scale (F.S.)
Response Time (T90): ≤25 seconds with waterproof breathable film
Resolution: 10 ppm
Repeatability: ≤±1% F.S.
Operating Temperature: -20℃ to 60℃
Storage Temperature: -40℃ to 85℃
Humidity Range: 0 to 95% RH
Warm-up Time: 1 minute
Digital Signal: Modbus RTU 38400 bps
Analog Signal: 0.4 to 2V
Power Supply: 3.3 to 6 VDC
Current: 45 mA (average), 180 mA (max)
Power Dissipation: 0.23 W (average)

Pin Functions:

V+: VCC+ 3.3 - 6V
GND: VCC-
Tx: Serial port transmitter, TTL level, 0 – 2.5V
Rx: Serial port receiver, compatible with 1.8-5V input
DA: Analog output, 0.2V indicates preheat, 0.4-2V corresponds to 0-100% F.S., 2.2V indicates overrange

Additional Features: The sensor is noted for its long life and regular 7-series size for ease of use.
