PM8915 Hot Wire Anemometer Handheld with Telescopic Probe, CFM/CMM Digital Wind Speed Meter Gauge, Air Flow Velocity Tester for Measuring HVAC, Duct Airflow, Wind Speed, Wind Chill

Key features

• High Sensitivity & Accuracy: The hot wire anemometer can measure extremely low airflow velocities, mesurement wind speed range 0 to 67 mph(±3%±0.2 of readings); wind temperature range: 32℉ to 113℉ / 0 to 45℃(1.8℉/±1.0℃); Resolution 0.01 mph; airflow(CFM/CMM) range 0 to 999900 ft/min
• Free Switching of Measurement Units: wind speed (m/s, km/h, ft/min, knots, mph), wind temperature (°C/°F) and airflow (CFM/CMM) *Calculate the CFM: Air Flow in CFM =Wind speed x Duct Cross Sectional Area
• Multifunctional: This Pro hot-wire wind speed meter has an LCD backlight display that shows the Beaufort scale, measures current, Max, Min, average, 2/3V max wind speeds, wind chill and low battery indicators, auto power off
• Non-Intrusive Measurement: The handheld anemometer telescoping probe can be inserted directly into the vent to take a reading before passing through the vent grille, and it does not obstruct the fluid flow during measurements, minimizing disturbances ideal for measuring airflow in tight spaces in heating, ventilation, ducts and air conditioning (HVAC) equipment, etc
• What's in the Box: 1x Digital hot-wire anemometer (stainless steel remote probe with a 9mm tip diameter, length 42" (1070 mm), cable length 66.9" (1.7m), and retractable length is 533 to 2100mm), 1x Hard Carrying Case, 1x USB Type - C Charging Cable, 1x Adjustment Certificate, and 1x Instruction Manual, If there is any quality problem, we will replace it for you for free
