T99-CO2W Transmitter Wall Mounted Carbon Dioxide Sensor

Ventilation control by CO2 is a viable and energy efficient way of controlling ventilation to target cfm / person levels based on actual occupancy.  The measurable rather than traditional approach of providing fixed ventilation is based on maximum occupancy. Designed for HVAC, ventilation systems, offices and other public places, this wall mounted transmitter uses NDIR technology and features a patented self-calibration system to guarantee the long term stability and up to 15 year life span.
