Made for HVAC professionals, Beha-Amprobe's TMA5 will do all the air measurements you need, and is still small enough to fit in your pocket!
The TMA5 can be used to measure air velocity, air temperature, humidity levels and can also calculate dew point, wet bulb, wind chill and ambient temperature. Temperature levels can be measured in either Celsius or Fahrenheit, while air be measured in knots, Beaufort, feet per minute, miles per hour, metres per second or kilometres per hour.
Fast responding with its own built-in vane, the TMA5's small size makes it ideal for use in ducts or other tight applications. It also comes with several additional functions, including a data hold facility which will freeze the current screen, max wind speed display, automatic power off when left idle and a wrist strap for easier holding.
