Designed for Professional Engineers
At the centre of the kit is the Testo 558s Digital Manifold. Its large colour touchscreen provides clear pressure, temperature, superheat and subcooling readings. Physical buttons also allow comfortable operation while wearing gloves.
The included Testo 115i wireless clamp thermometers and Testo 552i wireless vacuum probe connect directly to the manifold using Bluetooth. This creates a cleaner setup while reducing the number of hoses required during servicing.
For refrigerant charging, the Testo 560i refrigerant scale and intelligent refrigerant valve automatically control charging by weight, superheat or subcooling. This helps improve charging accuracy and reduces refrigerant waste.
The kit also includes the Testo 565i smart vacuum pump for automated evacuations, the Testo 770-3 Bluetooth clamp meter for electrical diagnostics and the Testo 316-3 refrigerant leak detector for locating refrigerant leaks quickly and accurately.
Bluetooth Connectivity
Every compatible instrument connects to the Testo Smart App, allowing you to view live measurements, create digital reports and save job data directly from your smartphone or tablet.
In addition, firmware updates can be installed over the air, helping keep your equipment up to date with the latest features and refrigerant support.
Built for Daily Site Work
