Product Overview
STH-CD5N_F is equipped with temperature·humidity sensor elements. This sensor is designed
for duct installation. It is easy to use in the field where the temperature and humidity need to be precisely
monitored such as the thermo-hygrostat, low-temperature warehouse. And It is a product that can
output temperature and humidity data as analog signals. In addition, by positioning the FND and
buttons on the front, you can easily control the temperature and humidity monitoring and setting of industrial
sites and equipment.
· Digital temperature·humidity sensor
·Monitoring with front panel FND
·Designed for air duct
·Temperature·humidity data analog signal output
