Air speed, temperature and moisture in one instrument Measures air flow and temperature – Flexibly and easily

testo 410

testo 410-1 measures air speedand temperature. It is ideal for spot measurements at air outlets on account of its 40 mm vane.Timed mean calclation ispossible.In addition to air speed andtemperature, testo 410-2 alsomeasures air moisture. Testo'sown, patented humidity sensor guarantees measurements you can build on. In this way, air conditions can be reliably checked. •Flow velocity measuringinstrument with temperaturemeasurement•Timed mean value calculation•Hold function and max./min.values•Windchill calculation for outsideareas (perceived temperature)•Display illumination

Attachable protective cap Flow measurement at a duct outlet with 40 mm vane

Additional b benefits o of t testo 4 410 - 2: •Air humidity measurement withlong-term stable Testo humiditysensor•Incl. dewpoint calculation andwet bulb
