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.
Product Features
Measurement Capabilities
Wide Pressure Range: -15 to +870 psi (-1 to +60 bar) with ±0.5% full-scale accuracy. 0.01 psi/bar resolution for detailed readings.
Hoseless Design: Direct connection to 7/16 in. UNF pressure ports, minimizing refrigerant loss.
Media Compatibility: Suitable for CFC, HFC, HCFC, nitrogen, water, and CO₂ systems.
Wireless Connectivity & App Functions
Bluetooth 4.0 Integration: Pairs with iOS/Android devices (range ~65 ft/20 m) for remote operation.
testo Smart Probes App: Auto-calculate evaporation/condensation temperatures. Data display as graphs/tables; export to PDF/Excel. Real-time monitoring for hard-to-reach pressure ports.
