INTRODUCTION
Pacer’s model DA40T digital thermometer-anemometer is a versatile instrument for measuring air velocity and
temperature of airflow from HVAC ducts or process air flow.
The heavy, all metal (except electronics) probe can be used for airstreams which have a wide range of humidity,
temperature and contaminants without compromising accuracy. Temperature sensor is a Platinum Resistance
Element (RTD).
Features include choice of probe diameters, custom cable lengths, tolerance of temperatures up to 210
˚
F
(98.9
˚
C) at the probe, and durability. Optional special-purpose temperature-only probes may be purchased from
factory.
