UEi In-Duct Anemometer and Psychrometer

2 items left

Description

The DAFM4 Anemometer/Psychrometer is designed with 6 HVAC/R parameters in one instrument. These are included in a portable, batteryoperated instrument for measuring humidity, air temperature, dew point, wet bulb, air velocity and air volume. The small vane probe includes sensors for velocity, temperature and humidity all on a telescoping extension, making in-duct and surface measurements possible.

Features

  • Measures air velocity, temperature, and relative humidity (RH%)
  • Calculates wet-bulb temperature, dew point, and air volume (CFM, CMM)
  • 0.7” Small diameter air vane on 39” long telescoping probe
  • Timed accumulative average for air volume with one hour maximum
  • Min/Max and Hold
  • English/Metric Scales
  • Fast response
  • Auto-power off (can be disabled)
  • Low battery indicator

Included

  • DAFM4 Meter
  • Remote telescoping mini-vane probe
  • Battery (1 x 9V)
  • User manual
  • Hard carrying case
