Testermeter-CO2 Transmitter in Temperature and Humidity OptionTS21-CO2

overview

A low-cost CO2+Temp or CO2+RH transmitter is designed for applications in HVAC, ventilation systems, offices, schools, and other public places. It can provide one or two 0-10V / 4-20mA linear outputs. Tri-color traffic display for three CO2 measuring ranges. Its Modbus RS485 interface can integrate devices to any BAS system.

Features

Real time detection of air carbon dioxide and optional temperature and humidity

NDIR infrared CO2 sensor with patented self calibration

Up to 10 years lifetime of CO2 sensor and longer T&RH sensor

One or two 0~10VDC/4~20mA linear outputs for CO2 or CO2 &Temp. or CO2&RH

LCD display with 3-color backlight for three CO2 measured ranges
