CO2 transmitter INS-TR-CO2-AF-4X1

Description
Monitoring CO₂ does not need to be complicated. The INS-TR-CO2-AF-4X1 is a CO₂ transmitter with display that shows real-time carbon dioxide concentration while transmitting data to your control system. Designed for professional environments, this transmitter meets the requirements of modern HVAC installations, commercial buildings and building management systems.

Immediate CO₂ readout
The integrated display provides a direct reading of CO₂ in ppm. No external device is required to check occupancy levels or indoor air quality.

Measurement ranges

• 0–5000 ppm
• 0–10000 ppm

Measurement performance
With a resolution of ±10 ppm and an accuracy of ±50 ppm + 2 %, this transmitter ensures reliable and consistent regulation over time.

An energy regulation tool
Installing a CO₂ transmitter with display enables optimized ventilation by automatically adjusting airflow to actual CO₂ levels:
