Description
Overview
The Fluke 971 Temperature Humidity Meter is a portable handheld instrument designed for professionals who need fast, practical measurement of temperature and relative humidity in indoor environments. It is positioned by Fluke for facility maintenance teams, utility technicians, HVAC service contractors, and indoor air quality specialists who need to monitor comfort conditions, troubleshoot problem areas, and verify environmental conditions during maintenance work. Fluke identifies the 971 as a temperature humidity meter that measures humidity and temperature, and also supports dew point and wet bulb temperature readings.
For HVAC, building maintenance, and IAQ work, temperature and humidity are closely linked to comfort, ventilation performance, condensation risk, and moisture control. The Fluke 971 helps technicians capture field readings without carrying a large instrument setup. Its backlit dual display allows humidity and temperature values to be viewed clearly, while its compact body, belt clip, protective holster, and protected sensor support practical field use.
The instrument is especially useful when technicians need to compare readings across multiple rooms, zones, storage areas, plant rooms, or controlled spaces. With 99-point record storage, Min/Max/Avg data hold, and a quick-response capacitance sensor, the Fluke 971 gives maintenance teams a convenient way to capture environmental readings during inspections and troubleshooting.
Key Features
- Backlit dual display for simultaneous humidity and temperature reading.

- Relative humidity measurement range from 5% to 95% RH.
- 99-point data storage for recording multiple readings.
- Min/Max/Avg data hold function for field comparison and trend checks.
- Quick-response electronic capacitance polymer film humidity sensor.
- 500 ms temperature update rate for responsive temperature measurement.
- Compact handheld design with protective holster and belt clip.
- Powered by 4 AAA alkaline batteries with a listed battery life of 200 hours.
Applications
The Fluke 971 Temperature Humidity Meter is suitable for building and environmental measurement tasks where reliable humidity and temperature readings are required. Fluke describes the product for professionals involved in facility maintenance, utilities, HVAC service, and indoor air quality assessment.
Common application areas include checking comfort conditions in commercial buildings, verifying HVAC performance after service work, identifying rooms with potential humidity issues, monitoring problem areas, assessing indoor air quality conditions, and supporting maintenance inspections. Distributor information also lists applications such as facility maintenance, utilities, HVAC/R, indoor air quality, and data center monitoring and maintenance.
Because the instrument measures relative humidity, ambient temperature, wet bulb temperature, and dew point, it can support practical field decisions related to condensation risk, moisture control, air-conditioning performance, storage environment checks, and general environmental troubleshooting. Grainger also lists measured properties including ambient temperature, dew point, relative humidity, and wet bulb temperature.
