Description
This handheld temperature and humidity meter, Fluke 971, simultaneously measures ambient temperature and relative humidity on a backlit dual display. The Fluke 971 shows temperature and humidity simultaneously and reports both dew point and wet-bulb temperature based on built-in sensors.Functions and measurement principles
- Backlit dual display for simultaneous viewing of temperature and relative humidity.
- Capacitance humidity sensor with fast response time for measuring relative humidity.
- NTC temperature sensor for measuring ambient temperature.
- Built-in calculations for dew point and wet-bulb temperature.
- Min/Max/Avg/Hold functions for quick assessment of measurement data.
Typical applications
- Used for measuring ambient temperature and relative humidity.
- Used for determining dew point and wet-bulb temperature from measured values.
- Used where simple data collection with up to 99 logged records is required.
