testo 440 – with high accuracy digital temperature meter

If you’re looking for a professional thermometer or temperature gauge, here’s a handy measuring set designed for insertion measurement. The instrument and the robust temperature sensor are extremely easy to use and also benefit from the intelligent calibration concept, which means you only send in the sensor part and keep the handle and the instrument when it is time to calibrate.

This measurement kit includes the testo 440 multi-instrument. 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.

All sensors that work with the testo 440 and testo 440 dP can also be used with the reference meter testo 400.
