7/7/11 - R1
Rugged 5-in-1 Environmental Meter
Measures Humidity, Temperature, Air Velocity, Light and Sound
Hygro-Thermo-Anemometer-Light-Sound Meter
Ordering Information:
EN300 ..........................Hygro-Thermometer-Anemometer-Light-Sound Meter
TP870 ..........................Type K Bead Wire Thermocouple
Features:
• 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 to freeze the displayed value
• Records Min/Max readings
• 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 sen-
sor 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
• Defaults to last function when powered off
• Auto power off 10 minutes after last
key is pressed with disable feature
• Low Battery and overrange indication
• Tripod mount
• RS-232 PC interface
• Complete with built-in Humidity, Light, Sound and
Temperature sensors, Vane wheel, windscreen, Type K
thermocouple probe, pouch case, and six 1.5V AAA
batteries.
