DH50 (Digital Hygro-Thermometer) is a versatile instrument for measuring temperature and relative humidity. Special features include a calculated dew point switchable between °F and °C. Also, the temperature reading is switchable between °F and °C. Included is a hold/reset button so that the display can be frozen when recording readings. Also, it can indicate maximum and minimum readings. This instrument is a must for anyone in the heating, ventilation, and air conditioning industry. Specific applications include environmental, air quality, and many others where accurate temperature and relative humidity measurements are essential.

    Features:
  • High accuracy due to the use of a microprocessor
  • Display of calculated Dewpoint in °F or °C
  • Digital memory for maximum and Minimum values
  • Temperature range switchable in °F and °C
  • Display hold for easy reading of measurements
  • Long battery life
