Medidor ambiental 4-em-1 Extech 45170 com velocidade do ar, humidade, temperatura e luz

The Extech 45170 is a 4-in-1 environmental meter that combines air velocity, relative humidity, air temperature, and light measurement in one handheld instrument. Its vane anemometer delivers air velocity readings from 0.4 to 30 m/s with ±3% accuracy, making it ideal for HVAC and indoor air quality checks.

Advantages

Dual LCD with backlight shows two parameters simultaneously. Data hold and min/max functions capture readings for later review. Auto power off with disable feature conserves battery life. Includes Type K bead wire probe for temperature measurements from -100 to 1300°C.
