Digital Hygro-Thermometer - DHM200

Data Acquisition for up to 1000 double measurements with manual save High accuracy Display of percent Relative Humidity Display of Temperature in °F or °C Display of Calculated Dewpoint in °F or °C Maximum and Minimum over current measuring session Maximum and Minimum over acquired values Serial output through standard RS232C Data-link Automatic display and battery test User-friendly keypad for simple operation 2 separate analog outputs

The Digital Hygro-Thermometer DHM200 checks relative humidity and temperature for the air conditioning, heating, and ventilating fields. This instrument also displays a calculated dew-point.
With the built-in memory up to 1000 double values can be stored and the collected data can be transmitted to a printer or PC through a RS232C interface.
