Made in Japan
Manufacturer: Watanabe Electric Industry Co. Ltd
Model: CD1-F-J

CD1-F-J is a duct-type CO2 sensor that is maintenance-free, low-cost, and long-life. The detection module based on the non-dispersive infrared absorption method (NDIR) has succeeded in miniaturization with the latest technology. A comfortable indoor environment is maintained by monitoring the CO2 concentration, contributing to a reduction in energy consumption.
