Smart Probes - Thermal Anemometer Operated with Smartphone testo 405i


Compact measuring instruments optimised for Smartphones.

Ideal for the mobile measurement of climate, cooling and temperature. They can be operated cableless with a smartphone or tablet and easily transported in the manageable testo Smart Case. Compact and ready-to-use. All measuring instruments are immediately connected to the free and usable testo Smart Probes App and can be read, recorded and subsequently sent per e-mail with a mobile device.

Smart Probes App:
  • Wireless reading of the measured values on a smartphone / tablet - also at some distance from the instrument.
  • Take readings from up to 6 Smart Probes at a time.
  • The app quickly shows up measured value changes - as graph or as table.
  • Application-specific measurement menus, e. g.: automatic calculation of evaporation and condensing temperature as well as from overheating and undercooling; volume flow measurements in channel / at outlet; non-contact temperature measurement via infrared with fast image capture incl. measured value and spot marking.
  • All measurement can be attached to the pictures created with the app and sent directly to your email account as PDF report or Excel file.
