Extech EN300 5-in-1 environmentálny prístroj: anemometer, hygrometer, luxmeter, teplomer, hlukomer

Measure air velocity up to 30 m/s (5900 ft/min) with ±3% accuracy, plus humidity, light, temperature, and sound level in one handheld meter. The EN300 combines five essential environmental measurement functions into a single instrument with a backlit dual LCD and vane-type anemometer.

Overview

The Extech EN300 is a versatile 5-in-1 environmental meter that measures air velocity, humidity, light, temperature, and sound level. It features a 5-digit dual LCD with backlight for clear readings in any lighting. Air velocity is measured with a vane sensor, light with a silicon photodiode, and sound with an electret condenser microphone. Data hold, min/max recording, and auto power off (with disable) enhance usability. Powered by a 9V battery.
