Measurement set with testo 440 for ventilation measurements with hot wire sensors

This measurement set includes the testo 440 ventilation and indoor climate meter. It can be connected to a wide range of digital sensors, testo SmartProbes and many other temperature sensors. Clearly structured measurement menus for duct/vent volume flow, k-factor, turbulence degree, cooling/heating load, moisture damage risk indication and logging function. These menus allow you to complete measurement tasks faster, more efficiently and more reliably. Reports can be exported as Excel files via the USB interface or printed on site.

This is a handy kit for measuring air speed, air flow and air temperature in ventilation ducts. The instrument and hot-wire sensor are extremely easy to use and very handy for adjusting ventilation systems. The intelligent calibration concept also means that you keep the handle and the instrument. Just detach the sensor part and send it to us when it is time for calibration.
