Product Description

CDTH series carbon dioxide ( CO2 ) / temperature / humidity transmitters are designed for monitoring & controlling indoor air quality, temperature and humidity in one unit
CDTHW is suitable for wall mount and CDTHD is suitable for duct mount
High performance NDIR digital sensor and circuit, ensure precise measurement and temperature compensation
Multiple optional RTD or thermistor sensors, compatible with a variety of control systems
Stable, reliable and fast response

15 years of CO2 sensor life without maintenance

All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring
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

*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

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.
