Description

Testo 549i Smart High-Pressure Gauge for Refrigeration Systems

Product Introduction

The Testo 549i is a compact, smartphone-operated high-pressure gauge designed for wireless diagnostics of air conditioning and refrigeration systems. With a measurement range of -15 to 870 psi (-1 to 60 bar), it enables precise pressure monitoring while eliminating the need for traditional hoses—reducing refrigerant loss during servicing. Controlled via the testo Smart Probes App, it auto-calculates evaporation/condensation temperatures and supports real-time data visualization, making it an essential tool for mobile technicians.
