The Fluke 971 Temperature Humidity Meter is a reliable tool for measuring humidity and temperature, making it suitable for professionals in HVAC, facilities management, and indoor air quality. One of its key strengths is its accuracy, boasting a measurement accuracy of +/-0.5%, which ensures that you get precise readings. The device features a backlit dual display, allowing you to see both humidity and temperature simultaneously, which is convenient for quick assessments in various lighting conditions. Additionally, it can measure dew point and wet bulb temperatures, providing comprehensive data about the environment.

The quick response capacitance sensor is another highlight, as it delivers fast and efficient readings, saving you time during assessments. Ergonomically designed with a belt clip and protective holster, this meter is easy to carry around, enhancing its portability. The storage capacity of up to 99 records is useful for tracking and analyzing data over time. However, the product does have some drawbacks. At 300 grams, it is relatively heavy compared to other handheld humidity meters, which might be a concern for prolonged use. Additionally, while the device includes a one-year warranty, some users may find this relatively short for a professional tool.

The Fluke 971 is powered by two AA batteries, which are included, but frequent use might require regular battery replacements. The device's dimensions (2.36 inches wide and 7.64 inches high) make it somewhat bulky for those who prefer more compact tools. In terms of additional features, the meter does not offer Bluetooth connectivity or smartphone integration, which are becoming standard in many modern meters. Despite these minor shortcomings, the Fluke 971 remains a reliable and accurate humidity meter suitable for professionals who require precise and quick environmental measurements.
