testo 550s Conjunto de manifold digital com Bluetooth e 2 sensores de temperatura de pinça sem fios (0564 5501)

The testo 550s digital manifold gauge set redefines refrigerant system diagnostics by combining a rugged 2-way manifold with Bluetooth connectivity and two wireless clamp temperature probes. Unlike conventional analog manifolds, this smart instrument automatically calculates superheat and subcooling in real time, eliminating manual calculations and reducing the risk of errors. The high-resolution graphic display presents pressure and temperature readings side by side, while the Testo Smart App enables remote monitoring, data logging, and report generation directly from your smartphone or tablet.

Highlights

• Measures high and low side pressure from -1 to 60 bar with ±0.5 % full-scale accuracy
• Supports 90 common refrigerants, updateable via the Testo Smart App
• Includes two testo 115i wireless clamp temperature probes for non-invasive pipe temperature measurement
• Bluetooth 5.0 connectivity for live data transmission and app-based analysis
• Rugged IP54-rated housing withstands harsh field conditions
• Long battery life of up to 250 hours (without Bluetooth and backlight)

In daily use

Designed for HVAC/R technicians, the testo 550s streamlines commissioning, troubleshooting, and maintenance of air conditioning and refrigeration systems. The three 7/16" UNF connections allow simultaneous connection to high side, low side, and a refrigerant cylinder or vacuum pump. The integrated temperature compensation ensures accurate readings even in fluctuating ambient conditions. With the Testo Smart App, you can create professional reports with measurement curves, add photos, and share them via email or cloud services. The included transport case keeps the manifold and probes organized and protected during transit.
