Extech Environmental Meter


This rugged 5-in-1 Environmental Meter measures Humidity, Temperature, Air Velocity, Light and Sound. Features include: a large dual LCD for simultaneously displaying Temperature and Air Velocity or Relative Humidity; Data Hold and Min/Max functions; a built-in low friction vane wheel which improves accuracy of air velocity, precision thin-film capacitance humidity sensor for fast response, and thermistor for ambient temperature measurements; characters on display reverse direction depending on Hygro-Thermo-Anemometer or Light-Sound Mode; utilizes precision photo diode and correction filter for Cosine and color corrected light measurements; auto power off 10 minutes after last key is pressed with disable feature; Low Battery and overrange indication; tripod mount; and PC interface with optional Data Acquisition Software. Type K input measures temperature up to 2372 degree F (1300 degree C). Sound Level measurement meets IEC class 2 using A frequency weighting and fast response time. Comes complete with built-in sensors, Vane wheel, windscreen, Type K thermocouple probe, pouch case, and six 1.5V AAA batteries. Specifications: Range: Air Velocity: 80 to 5910 ft/min, 0.4 to 30m/s, 1.4 to 108km/h, 0.9 to 67 MPH, 0.8 to 58.3 knots. Light: 0 to 1860Fc, 0 to 20,000Lux. Relative Humidity: 10 to 95 percent RH. Temperature: Thermistor, 32 to 122 degree F (0 to 50 degree C); Type K, -148 to 2372 degree F (-100 to 1300 degree C). Sound: 35 to 130dB, 31.5 to 8,000Hz, A weighting/fast response.
