Extech EN300

5-in-1 Environmental Meter

The EN300 Measures Humidity, Temperature, Air Velocity, Light and Sound. Rugged 5-in-1 environmental meter with tripod mount and RS-232 PC interface. Large dual LCD simultaneous display of Temperature and Air Velocity or Relative Humidity. Characters on display reverse direction depending on Hygro-Thermo-Anemometer or Light-Sound Mode. Data Hold, Min/Max, Auto power off, Low Battery/Overrange indication. Built-in low friction vane wheel improves accuracy of air velocity in ft/min, MPH, m/s, km/h, and Knots. Built-in precision thin-film capacitance humidity sensor for fast response. Built in thermistor for ambient temperature measurements. Type K input measures temperature to 2372° (1300°C). Utilizes precision photo diode and correction filter for Cosine and color corrected light measurements. Sound Level measurement meets IEC 61672 class 2 using A frequency weighting and fast response time. Complete with Type K thermocouple probe, pouch case, and six 1.5V AAA batteries.

Extech EN510

10-in-1 Environmental Meter

The convenient Extech EN510 is a 10-in-1 environmental meter that can measure air velocity, air flow, air temperature, Type-K temperature, heat index, and humidity. It also offers wet bulb, dew point, windchill, and light level measurements. The EN510 includes a built-in, replaceable low friction ball bearing mini vane wheel, a precision photo diode with cosine and color correction filter, and a capacitive humidity sensor for high accuracy. The Type-K input accepts standard Type K Thermocouple probes to measure surface temperature up to 1300°C (2372°F). The large dual LCD display is backlit for easy use in dimly lit areas, and auto power off (with disable) helps save the battery.
