Anemometers & Flowmeters

The Amprobe TMA-us.htmlHW hot-wire anemometer measures air flow volume and velocity, has a telescopic probe for positioning the sensor, and is used by HVAC/R technicians to measure wind flow and temperature in air conditioning systems. The hot-wire sensor eliminates moving parts for more consistent results. Air velocity is measured in feet per minute (ft/min), and meters per second (m/s), knots (KNT), kilometers per hour (km/h) and miles per hour (mph). Air flow volume is measured in in cubic meters per second (CMS) and cubic feet per minute (CFM). The dual-scale thermistor temperature sensor measures temperature in F and C. The meter has minimum, maximum, average, and hold functions for recording data. The meter requires six AAA batteries (included), and includes a hard-sided carrying case, and instructions.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Anemometers measure air speed, and in some cases airflow and air direction. They are used in field and lab applications.
