Extech EN300 5-in-1 Environmental Meter

The Extech EN300 5-in-1 Environmental Meter is capable of measuring air velocity, light, relative humidity (RH), temperature and sound levels. The EN300 is able to be mounted on a trip and RS-232 PC interface. The large, dual LCD display simultaneously shows temperature and air velocity or relative humidity readings. Some functions of the device include data hold, minimum/maximum display, auto power off, low battery indication and over range indication. Air velocity is measured via a low friction vane wheel built into the bottom of the device which increases measurement accuracy. A thermistor measures ambient air temperature while the Type K thermocouple measures surface temperatures up to 2372 °F (1300 °C). A precision photo diode measures illuminance in both lux (lx) and foot-candles (fc) and the sound level meter meets IEC 61672 Class 2 ratings. For accurate measurements of a variety of different physical quantities, the Extech EN300 is an ideal choice.
