FEATURES: Measurement of current speed, temperature, and air humidity. Measurement of current air flow volume, maximum/minimum speed and flow measurement, average value measurement and 2/3 of the air flow value. Selection of appropriate units for speed, volume, and air temperature. Measurement of direction and angle of air movement. Real-time measurement when connected to a computer. User-friendly computer software. Screen with backlighting and current measurement hold function. Low battery indicator. Auto shutdown.

DURABLE AND ERGONOMIC CASE: Provides durability and shock resistance. 4 x AAA 1.5 V BATTERIES: Four batteries positively affect the device's operating time, ensuring a long lifespan.

TELESCOPIC MEASURING STICK WITH COMPASS: The measuring stick with a flexible cable and extendable - telescopic neck facilitates access to measurements in hard-to-reach positions. The compass allows the display to show wind direction relative to the rotor.
