Accuracy: see accuracy table
Hysteresis: <±1%RH
Response time: <10s (25°C, in slow air)
Drift: <±0.5%RH/year
Output: 4~20mA, 0~10V, RS485/Modbus
Power supply: 16~28VAC/16~35VDC
Load resistance: ≤500Ω (Current output),≥2kΩ (Voltage output)
Display: Optional LCD Display (CDTHW)
Display resolution: 1ppm, 0.1°C, 0.1%RH
Working environment: 0~50°C, 0~95%RH (Non-cond.)
Temp. compensation: 0~50°C
Storage temperature: -20~60°C
Housing material: ABS+PC (CDTHW), fireproof ABS(CDTHD)
Protection: IP30 (CDTHW), IP65 (CDTHD)
Approval: CE
*ABC algorithm: Automatic Baseline Correction, it constantly keeps track of the sensor's lowest reading over a few days interval
and slowly corrects for any long term drift detected as compared to the expected fresh air value of 400 ppm CO2.
1. All products are factory set to 0-10V as output default, and can be set to 4-20mA by jumper on the PCB
*2. See resistance table on page 1 of this catalog.
Accuracy table for temperature/ humidity
*When select RTD/ thermistor, total error will be 0.5°C more than the accuracy in the models
