Product Details
CO₂ Transmitter (Duct-mounted Type) KGD - AM - 112
Product Introduction
The KACISE Optoelectronic CO₂ transmitter is a cost-effective and
high-precision CO₂ transmitter. It can monitor the CO₂
concentration in real time and transmit the CO₂ concentration
values to the ventilation system in real time through industrial
standard analog signals (4~20mA/0~10V), so as to control the air
quality and maintain a comfortable and healthy indoor air
environment. It has the ABC self-calibration function and can
maintain stable operation without drift for a long time.
Product Features
- NDIR technology with independent intellectual property rights.
- Fast response, capable of real-time monitoring of CO₂
concentration.
- High precision, meeting the RESET standard.
