Features:
- 4-20 mA (3 wire) or 0-10 VDC output, selectable via jumper
- 24V AC / DC power supply
- Measures 0 – 2000 ppm
- Up to 15 years life time
- Non-dispersive infrared detector (NDIR)
Application/s:
- Office premises
- Airports
- Hotels
- Conference rooms
- Hospitals
- Schools
Overview:
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.
