Testo 550i Smart Kit Digital Manifold (with 2x 115i Wireless Clamps)

The Testo 550i Smart Kit is a fully app-controlled, 2-valve digital manifold system engineered for modern refrigeration, air conditioning, and heat pump diagnostics. Built with a robust IP54-rated housing, the manifold communicates directly with the Testo Smart App via Bluetooth (up to 150m range) to deliver live pressure and temperature readings to your smartphone or tablet. This kit includes two wireless Testo 115i clamp thermometers, enabling automatic and highly accurate superheat and subcooling calculations on site. The 550i is compatible with A3 and A2L refrigerants (such as R32) and integrates seamlessly with the broader Testo range and Bluetooth Smart Tools collection.
