  • Measurement of flow velocity and air volume flow rate and temperature
  • Simple configuration of duct geometry and dimensions to calculate air volume flow rate
  • Detection function for areas potentially affected by humidity
  • Telescopic probe with a maximum length of 400mm
The SmartProbe kit designed for the VAC sector enables measurement of all parameters necessary for the regulation of the VAC system, such as flow rate and airflow, humidity and temperature. The kit comes with a handy carrying case that holds all the necessary measurement technology.

The SmartSond kit connects to a smartphone and provides all the necessary measurements during installation, adjustment and service work in ventilation and air conditioning systems.

The complete set consists of the testo 405i thermoanemometer, testo 410i wind anemometer, testo 605i thermohygrometer and testo 805i pyrometer. The SmartSondes connect wirelessly to a smartphone or tablet.

The kit is ideal for measuring air flow and airflow, humidity and temperature with its intuitive mobile app. The kit includes a handy carrying case that holds all the necessary measurement technology.

The measured values are conveniently displayed on a mobile device such as a smartphone or tablet.

The device can read flow velocity, temperature and humidity via a mobile app. Parameters such as air flow rate, dew point temperature, wet thermometer temperature are also automatically calculated. In addition, all the necessary calculations, such as time averaging or multi-point averaging, help in daily operation.

Using the mobile application, the results are presented in the form of a list, chart or table. They can be sent via email, as a PDF or Excel file. All of this will save your valuable time by significantly increasing productivity.

Minimum smartphone requirements:
- iOS 8.3 or later
- Android 4.3 or later
- Bluetooth 4.0
The SmartProbe Kit for VAC systems consists of the testo 405i, testo 410i, testo 605i and testo805i in a handy carrying case, batteries and factory calibration protocols.
