Dew-point instrument　TMM-100

This equipment is the dew-point instrument which measures the dew-point temperature and dry-bulb temperature, and consists of the dew-point detection unit and the dew-point temperature measurement unit.
The dew-point temperature measurement unit can digitally display the dew-point temperature and dry-bulb temperature detected by the sensor and output the value as an analog voltage signal.
Since the detection unit and the dew-point measurement unit can be installed separately, it is suitable for applications such as checking the condition of another room where the detection unit is installed.
