Handheld Temp/RH Meter

• Displays Temperature, RH, Dewpoint
• °C/°F Switchable
• Maximum/Minimum Recall, Display Hold
• Optional Analog Output (0-1 Vdc)
• Optional Rechargeable Batteries/Charger

The RH71 is a low cost microprocessor based digital hygrometer/thermometer for measuring temperature, relative humidity, and dewpoint. Special features include reading temperature/dewpoint temperature in degrees F or C, a hold/reset button for holding the display readings, and a max/min button for storing the maximum or minimum readings. Also available is a optional 0-1 vdc analog output for both temperature and humidity which can go to a recorder, as well as a option for using rechargeable Ni-Cad batteries with recharger.
