It consists of a Testo 405i thermal anemometer, Testo 410i vane anemometer, Testo 605i thermo-hygrometer, Testo 805i IR thermometer, smart case batteries and calibration protocol.  The two types of anemometers give you the capacity to measure in-duct air flows as well as the flow rates from grilles or diffusors. Using the IR temperature probe you can measure surface temperatures on system components such as motors, and the thermo-hygrometer will provide an assessment of the humidity and dewpoint values throughout the systems being inspected.
