The HN-C series is reliable and accurate temperature/ humidity meter with the measuring humidity range of 0 to 100%RH by using a new developed humidity sensor.
Models with temperature output of 3-wire type Pt100 is available.Wall-mounting type, separated type and insertion type are prepared for various applications.
Heat-resistive separated type is available for using in the environment of -40 to 180°C.
