With a compact design and intuitive user interface Fluke 971 Temperature Humidity Meters are designed to provide optimum performance, quick test results and reliability. Whether it's in the inside buildings or outside environment Fluke 971 is the perfect tool for determining the state of humid air.

Packed in its own lightweight case, the portable Temperature Humidity Meter is ready to start measurements anywhere. Simply press the power button and the screen will display the relative humidity reading as well as the temperature in degrees Celsius or Fahrenheit. The Hold button will save your screen keeping the last reading that you’re taking with 971 Fluke Temperature Humidity Meter. In ambient mode the meter measures current temperature, Dew Point and Wet Bulb Temperature.

Another key feature of the Fluke 971 Meter is that you can store up to 99 readings. To save the reading simply press the save button once!
