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.

MIN at E is lower than the 1st MIN, registered at B, and will replace it. F) The zero crossing at F does not form a MIN and will be ignored. This protects against false MIN readings when the probe is withdrawn from the air stream. DA40T User Manual Pacer Instruments, Inc Rev 1.0 www.pacer-instruments.com...
Volume flow = Air Velocity x Area, therefore, Volume flow rate = 450 FPM x 2 sq ft. = 900 CFM.
