Specifications

Product Description

CDTW: Wall mount CO₂ & Temperature 2 in 1 Transmitter optional with LCD or without LCD

CDTD: Duct mount CO₂ & Temperature Transmitter

Applications & Features

CDT series carbon dioxide ( CO₂ ) & temperature transmitters are designed for monitoring & controlling indoor air quality and temperature
CDTW is suitable for wall mount and CDTD 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(CDTW), display carbon dioxide(CO₂) and temperature alternatively (no temperature display for RTD or thermistor models)

Specifications

Storage temperature: -20~60℃

Housing material: ABS+PC(CDTW), fireproof ABS(CDTD)

Protection: IP30 (CDTW), IP65 (CDTD)

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.
