Fluke 971 – Fluke Indoor Quality Meter

Understanding and regulating a home’s heating and ventilation can do wonders for sinuses, clearing passageways and allowing inhabitants to breathe freely. Indeed, multiple studies have demonstrated that relative humidity has a major impact on a wide range of health conditions. Measuring humidity is very crucial for persons whose doctors have prescribed a controlled-humidity environment, whether the humidity is lowered or raised. Measuring humidity is also significant for non-health-related (but perhaps equally important) concerns like as wine and cigars. Rather than guessing the moisture level in your home, use a humidity meter to keep the moisture needle in the correct position. The best humidity meter, whether analog or digital, detects and reports the quantity of humidity in the air.

How to use Fluke 971

After removing the protective shutter from the sensor, push the power button to turn on the Meter and begin gathering measurements. Temperature readings can be shown in either the Scales in degrees Celsius (°C) or Fahrenheit (°F). Remove the battery compartment door and slide the temperature scale switch to the selected scale to switch between °C and °F.


To examine the saved Minimum, Maximum, and Average readings, press N again to cycle through all three stored sets of observations. You must first select a wet bulb, dew point, or ambient before reading the Min Max Avg data. The display displays which stored set of readings is displayed. Pressing N a fourth time displays the current measurement.


To exit Min Max Record mode and return to regular operation, press and hold N for two seconds.


When enabled, Min Max Record saves a new measurement that is either greater or less than a previously saved maximum or minimum measurement. To begin Min Max Record, press N. The letter M shows on the display to indicate that the Min Max Record mode is active.
