The Triplett Model AM320 Thermo-Anemometer + IR measures Air Velocity up to 5906 ft./min (30 m/s)， Air Flow (Volume) to 999，999 CFM/CMM， Air Temperature (140°F/60°C)， plus non-contact Infrared Temperature for use in HVAC System installation and maintenance， cleanrooms， kitchen exhaust systems， wind power monitoring， construction， sailing/boating， vehicle aerodynamics and many other applications. The built-in non-contact IR Thermometer measures remote surface temperatures up to 500°F (260°C) and has an 8:1 distance to spot ratio and laser pointer to identiy the target area. Easy to set Area dimensions (sq.ft or sq. m) are stored in the meter's internal memory for the next power on. 20 point average for Air Flow. Min/Max recalls highest and lowest readings. Data Hold freezes the reading on the display when taking measurements in areas where the display cannot be easily viewed. The auto power off (with disable) function conserves battery life. Includes vane sensor with 3.9 ft. (120 cm) cable， 9-Volt battery， protective rubber holster and Cert. of Traceability to NIST. 1-year warranty.
