1.1 Product overview
The transmitter is widely used in air quality detection equipment, fresh air ventilation system, smart home and other occasions that require CO and temperature and humidity monitoring. The input power supply, sensor probe and signal output of the sensor are completely isolated. It is safe and reliable, beautiful in appearance and easy to install.
The sensor uses a more advanced and expensive electrochemical probe, which has higher accuracy and stability than traditional semiconductor probes.
1.2 Features
This product uses a highly sensitive gas detection probe with stable signal and high precision. It has the characteristics of wide measuring range, good linearity, easy use, easy installation and long transmission distance.
