GS-CO2-xx-S-UN CO2 Transmitters
  • GS-CO2-xx-S-UN CO2 Transmitters

GS-CO2 Space Mounted CO2 Transmitters

Quick Overview

The GS-CO2 is a non-dispersive infrared sensor for measuring CO2 concentrations in controlled spaces. The GS-CO2-S is designed for use in indoor spaces to monitoring Carbon Dioxide levels using a microprocessor based electronics and a unique self calibration algorithm to improve long term stability and accuracy. It is ideal to ensure adequate ventilation while maximizing energy savings by ventilating at the optimum level. Units are also available with integrated temperature and relative humidity sensors to provide additional parameters. These units are ideal for monitoring CO2 levels, temperature and RH in commercial buildings, laboratories and public spaces. Units can provide either a 4-20mA or 0-10V output, LED indicators and LCD display.
