Output: 4~20mA, 0~10V, RS485/Modbus
Temperature
Sensor: Digital, RTD or thermistor, see models
Range: 0~50°C
Accuracy: see accuracy table
Output: 4~20mA, 0~10V, RS485/Modbus or RTD / thermistor
Relative Humidity
Sensor: Digital polymer
Range: 0~100%RH
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
Digital technology applied, multiple outputs optional, over voltage and reverse polarity protection, high reliability and
anti-interference capability
Large LCD with unit indicator( CDTHW ), display carbon dioxide (
CO2 ), temperature and humidity alternatively

Company Profile
Founded in 2011, Beijing Ifpen Instrument Enterprise, which is
adjacent to the beautiful political and cultural center, is located
in Beijing Daxing Industrial Development Zone. Our company has a
professional, innovative technical team and a standardized
production team. Over the years, we have been achieved zero
breakthrough in turbulence jump by committing to the production and
R&D of industrial instruments and meters and focusing on the
R&D and exploration in the field of "wind speed and air
volume". After the continuous evolution of the hot ball, hot wire
and hot film principles, as well as the exclusive secondary
calibration method, we are well-known in the industry as high
precision and high stability, breaking the conventional method of
using the differential pressure principle to detect air volume in
the traditional industry and breaking through the error value of
micro wind speed measurement. IVAN has persisted in serving new and
old customers with "Innovation, Quality, Integrity" since its
foundation. "The heart of innovation, serving the world", IVAN
focuses on R&D, provides high-quality products and services,
and is committed to the quality road of production enterprises.
