Testo 605 i - Thermo-hygrometer Smart and Wireless Probe


The testo 605i Smart Probe thermo-hygrometer is a humidity and temperature measuring instrument that quickly and accurately measures relative humidity. dew point. and temperature in rooms. ducts. registers. and environmental boxes/chambers.

Key Features:

  • Quickly and accurately measures relative humidity and temperature in rooms. ducts. and chambers
  • Automatically calculates dew point & wet bulb temperature
  • Small diameter probe is ideal for in-duct measurements
  • For all HVAC/R technicians and contractors


Users can read the measurements using
the testo Smart Probes App installed on their smart device. Smart Probes can be used individually or combined with other Smart Probes to create measuring solutions for most HVAC/R applications. Great for setup and diagnostics
of large and small HVAC/R systems!
The testo 605i works on smart devices with either Android or Apple operating systems.
The testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six (6) Smart Probes and easily document/report the results. Automatic calculations make it a snap!
All measurement data is displayed as instrument readings. tables. or graphs. The measurements can be quickly saved as PDF or Excel files. The App creates custom reports which can be saved and/or shared by email. All your data can be stored and retrieved saving you hours of time
consuming paperwork!
