Extech EN300 5-in-1 Environmental Meter

The Extech EN300 is a 5-in-1 environmental meter that allows users to test humidity, temperature, air velocity, light and sound levels all with one compact instrument.

The Extech EN300 environmental meter has a built-in vane anemometer for making quick and accurate air velocity readings. The high precision humidity sensor has a rapid response time for effortless readings of relative humidity. To acquire sound and light level readings is as simple as pointing the EN300 tester in the desired direction.

The large LCD allows the Extech EN300 to simultaneously display temperature readings with air velocity or relative humidity values, while in Light-Sound mode the characters reverse direction so that they can still be clearly read when the EN300 meter is rotated to measure light intensity and sound levels.

The Extech Hygro-Thermo-Anemometer-Light-Sound Meter is an extremely versatile device that allows accurate diagnostics to be made of various environments from solving HVAC problems to assessing the safety of working conditions.
