The Triplett Model AM320 Thermo-Anemometer + IR measures Air Velocity up to 5906ft/min (30m/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 identify the target area. Easy to set Area dimensions (ft² or m²) are stored in the meter’s internal memory for the next power on. 20 point average for Air Flow. Min/Max recalls the 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 3.9ft (120cm) cable, 9V battery, protective rubber holster, and Cert. of Traceability to NIST. 1-year warranty.
