Humidity computation unit HN-G (Japan Only)

The HN-G series is a temperature/humidity computation instrument that switches and display outputs six types of humidity unit in one unit by combining it with the HN-C series temperature/humidity meter, the R220/320 series of temperature/humidity transmitters, and the HN-Z series of high-temperature hygrometers.

6 types of humidity unit switching computation

Absolute humidity, relative humidity, mixing ratio, water vapor pressure, comparative humidity and dew point can be display and output in six humidity unit.
(In the case of HN-GRB, unit can also be converted to wet bulb temperature, so HN-GRB can be switched between seven types of unit.)
HN-GVA can supply 24V DC power for sensors
Temperature and humidity are each equipped with analog output and four contact outputs.
option communication interface available
