Ideal tool for balancing home HVAC, measuring air output and input, testing dust collection systems, checking heating and cooling equipment, diagnosing the proper functions of household and industrial appliances. Temp Units Optional: ℃/℉ Wind Temp Range: 32.0 ℉- 113.0℉ Wind Velocity Range: 0.001~100 mph Speed units: m/s, km/h, ft/min, knots, mph Wind Volume: 0-999,900m3/min ; 0-999,900 ft3/min Free Comupter Software for Win 7 / XP / 10 Connect BT-856A wind indicator with PC, allows you to monitor, transmit, record, save and analyse measurement data of wind wind velocity, temp, volume, Max/ Min/ (2/3)Max/ Average/ Current value at the same time. It will automatically generate a graph for the wind data, so you can know the change of wind condition with a glance. Extendable Wand + Cable Allows you to measure wind speed, air flow from higher and further areas that may not be accessible if you use a integrated anemometer. Separated Air Flow Sensor The handheld wind impeller sensor plugs into the main body, and if it is broken accidentally, you can replace it easily. Low Friction Impeller A low friction impeller can help you pick up the low winds down to 0.001 and give you an accurate reading. Easy to Read Out Simultaneously display air flow or air velocity plus wind temperature reading on large backlit LCD screen. Review: full featured! - works as expected ,easy to use, good software (windows 10 only supported) and is accurate. Review: Better then other ways. - Like it overall, would not take a good drop for sure. Handle is smooth plastic, needs some friction tape or something to keep from slipping out of hand. Trying to hold and push the buttons in sequence to get an average reading is a little tough. Better to memorize them and write down. Seems good for quick checking, after all , it is still guessing without a full hooded flow meter for accurate readings. But does the job as reference readings. ## Features - ➤【Pro HVAC CFM Anemometer】 This anemometro can accurately measure Wind Speed in 5 units:m/s, km/h, ft/min, knots, mph; Wind temperature in ℃/℉Celsius,Fahrenheit; Wind flow in CFM CMM.
