Measures Humidity, Temperature, Air Velocity, Light and Sound
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.
