The Thermohygrometer Model HD2301.0 is a portable instrument that measures an environment's temperature and relative humidity. It is fitted with a large LCD display for excellent visualization of the measured data. When the combined humidity/temperature probe is connected, the instrument calculates and displays the absolute humidity, dew point, partial vapour pressure.
