In combination with a smartphone or tablet, it allows for the measurement and verification of all temperatures and pressures of the heating system. Users can easily read their measurement values via the app installed on their device. For IR temperature measurement, such as with underfloor heating, the app enables documentation of the measurement with an image, temperature reading, and measurement spot marking. Additionally, it is just as quick to change the displayed measurement values. Application-specific menus, such as pressure drop tests including alerts, assist heating technicians in their daily work. All measurement data can be displayed either as a graph or in table form. Finally, the measurement data log can be sent directly via email as a PDF or Excel file. The handy testo Smart Case allows for easy transport of the measuring devices, ensuring they are always available when needed.
