testo Smart 4+

- All in one: The testo Smart App guides you easily and quickly through measurements on refrigeration, air conditioning and and heating systems.
- Fast: Graphically descriptive display of measured values, e.g. as a table, for quick interpretation of results.
- Efficient: Create digital measurement reports incl. photos as PDF/ CSV files on site and send them via e-mail.

NEW in the testo Smart App:
- Multi-site measurement PRO measurement program: With this first-class measurement program, you can simplify and professionalise the documentation of your measured values at different measurement sites.
- Air balancing PRO measurement program: Accelerate your workflow and eliminate errors: The new measurement program "Air balancing" brings you more efficiency and speed in the commissioning and adjustment of ventilation and air-conditioning systems (especially for balanced ventilation systems).

The testo Smart App is compatible with the following Bluetooth®-enabled measuring instruments from Testo:
- All Testo Smart Probes
- Digital manifolds testo 550s/557s/550i/570s and testo 550/557
- Digital refrigerant scale testo 560i
- Vacuum pump testo 565i
- Flue gas analyser testo 300/310 II/310 II EN/310 II EN
- Vacuum gauge testo 552
- Clamp meter testo 770-3
- Volume flow hood testo 420
- Compact HVAC measuring instruments


Applications with the testo Smart App
Refrigeration systems, air conditioning systems and heat pumps:
- Leak test: Recording and analysis of the pressure drop curve.
- Superheat and subcooling: Automatic determination of condensation and evaporation temperature and calculation of superheat / subcooling.
- Target superheat: Automatic calculation of target superheat
- Automatic refrigerant charging by weight, by superheat, by subcooling
- Vacuum measurement: Graphical progress display of the measurement with indication of start and differential value


Indoor air quality and comfort level:
- Temperature and humidity: Automatic calculation of dew point and wet bulb temperature


Ventilation systems:
- Volume flow: After the intuitive input of the duct cross-section, the app calculates the volume flow fully automatically.
- Diffuser measurements: simple parameterisation of the diffuser (dimensions and geometry), comparison of the volume flows of several diffusers when setting up a ventilation system, continuous and multi-point average calculation.


Heating systems:- Flue gas measurement: Second screen function in combination with testo 300
- Measurement of gas flow and static gas pressure: Also possible parallel to the flue gas measurement (delta P)
- Measurement of flow and return temperatures (delta T)
