With the Testo 550s Basic Kit (0564 5501 01) you’ll be set to install, service, & maintain refrigeration, air conditioning, & heat pump systems straight away. This kit comes with the Testo 550s Smart Digital Manifold with 2-way valve block, which has a large graphic display, a compact and robust housing, guided measurement menus and Testo Smart App access making it one of the best hvac digital gauges.

Also, what sets this basic kit apart is the two wired NTC temperature clamp probes included, which connect directly to the manifold and attaches quickly and easily to pipes ranging in diameter from 6 to 35 mm. These fixed cable clamp probes accurately measure surface temperatures on heating system pipes, water pipes, refrigeration systems or heat pumps. It can also calculate superheating and subcooling on refrigeration systems, but also determine flow and return temperatures in heating technology. The probe’s fixed cable has built-in kink protection – making it exceptionally robust & break-proof.

Testo delivers top-quality measurement technology and a high degree of reliability in these digital hvac gauges. In addition, smart functions for quick, easy measurements & documentation make the Testo 550s Basic Kit a reliable partner.

Simple and easy to use

A good upgrade from my 550 but the battery doesn't last as long, probably because of the screen upgrade.
