Introduction Extech EA25

Dual display of RH, Temperature, Dew Point, and Wet Bulb

The Extech EA25 Hygro-Thermometer and Datalogger data logs up to 15,000 records for PC download. Display any two parameters (Temperature and Humidity or Dew Point, or Wet Bulb) simultaneously. Min/Max function stores and recalls highest and lowest readings and displays the elapsed time to the minimum and maximum readings. Programmable auto power off. Switchable °C/°F temperature units. Data Hold function freezes reading on display. Complete with built-in stand, protective holster, and probe with 39 in. coiled cable, software and optically isolated RS-232 cable, and 6 AAA batteries.
