Smart Probes - Thermal Anemometer Operated with Smartphone testo 405i

Volume flow measurement
 Smart Probes app overview of basic functions
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.
