Hot Wire Anemometer with Telescopic Probe

Handheld Hot Wire Anemometer is a compact, accurate and robust device for measuring air velocity, volume, flow and temperature. Telescopic hot wire probe is designed to minimize the turbulence effect for in-duct measurements, and is well suited for low-flow applications. The probe features a rubberized ergonomic grip and extends/retracts from 10 to 38 inches. Timed and multi-point average flow calculations and in-duct air balancing with fast response time are enabled thanks to the depth and direction indicators. Other features include switchable metric/imperial measurements, min/max and hold functions, backlit LCD display, tripod mounting hole, auto power-off and a magnetized mount for hands free operation. Rubber o-rings are also included for marking duct depth on the wand. Measures velocity, volume flow (cmh, cmm, cfm, I/s) and temperature Duct temp. change has limited impact to reading accuracy Timed & multi-point average flow calculations In-duct air balancing with fast response time Depth and direction indicators on probe Magnet and tripod mount for hands-free operation Includes meter, (4) AAA batteries, hard carrying case, magnetic or tripod mount,  rubber o-rings and instructions.
