EXTECH RH350 SuperHeat Psychrometer

EXTECH RH350 SuperHeat Psychrometer simultaneously displays % relative humidity, temperature, and dew point or wet bulb or external temperature probe. The superheat differential measurements are T1-T2, Air-T1, T1-dew point, and the dual type K external temperature probe inputs (T1, T2). The unique sensor cap design twists to closed position for protection during storage.

meter retrieves max/min readings with data and time plus average function. The built-in RS-232 interface uses the optional compatible software to connect to a PC for futheranalysis of data points. Additional meter features includes switchable °F/°C temperature units with 0.1° resolution, real time clock, automatic power off, and data hold that freezes current readings on the display.
