The Extech Instruments RH25 is a Heat Index Psychrometer which will measure Temperature and Relative Humidity (using a precision capacitance RH sensor). The RH25 also calculates and displays Heat Index, Dew Point, Wet Bulb, and Wet Bulb Globe temperatures.

The High Temperature Alarm feature alerts the user when Heat Index or Wet Bulb Globe levels exceed user-preset limits.

Data Hold and MIN/MAX/AVG memory utilities make it easier to recall important data.

This device is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
