INTRODUCTION
The DAFM4 Anemometer/Psychrometer is designed with 6 HVAC/R
parameters in one instrument. These are included in a portable, battery-
operated 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.
