Extech EN300 Hygro-Thermo-Anemometer-Light-Sound Meter

Five meters in one! This is the Extech EN300, a multifunctional environmental tester which can be used to test humidity, temperature, air velocity, light and sound levels, making it an essential for comprehensive environmental surveys.

The EN300 is packed with functionality; it can test air velocity levels in ft/min, m/s, kmh, MPH and knots; it tests light in foot candles and lux; it simulataneously measures temperature and humidity levels and it's also a fully functional class 2 sound meter with A frequency weighting and fast response times.

All the sensors are integrated directly into the meter - it includes a low friction vane wheel for measuring air velocity, a precision thin-film capacitance sensor for fast response humidity readings, a thermistor for measuring temperature, a precision photo diode and correction filter for light and an integrated microphone for calculating sound levels. You can easily switch between any mode as needed; with the Extech EN300, there's absolutely no need to carry around multiple meters, as this one can do it all.

There's so much more to the EN300 too; this meter includes data hold and MAX/MIN functions, a type K input for direct surface temperature measurements using the included thermocouple probe, automatic power off and is even compatible with tripods (requires optional TR100 tripod) and can interface with your PC to download results (requires data acquisition software, part number 407001).
