Ducted Carbon Dioxide (CO₂) Transmitter with NDIR Sensor
High-precision CO₂ transmitter using an imported NDIR infrared sensor for duct or pipeline monitoring. Offers long service life, excellent stability, and waterproof protection — ideal for HVAC, factory, and laboratory environments.
The Ducted Carbon Dioxide (CO₂) Transmitter is designed for accurate, long-term measurement of CO₂ concentration in ducts, pipelines, and enclosed environments. It uses the non-dispersive infrared (NDIR) principle, where CO₂ is detected by its specific absorption of infrared light. This provides superior accuracy, repeatability, and long-term reliability compared with traditional electrochemical sensors.
Equipped with an imported high-performance NDIR sensing module, the transmitter delivers fast response, excellent stability, and over five years of service life without drift or oxygen dependence. The waterproof and breathable membrane design prevents condensation and dust from entering the sensing chamber, ensuring accurate readings even in harsh or humid conditions.
With a wide power supply range, high protection rating, and robust construction, this transmitter is ideal for industrial duct monitoring, HVAC control, laboratories, workshops, and CO₂ ventilation management systems.
