The Testo 549i is an intelligent wireless pressure meter designed for air conditioning and refrigeration systems, offering unparalleled mobility and convenience during servicing, trouble, and installation. This handheld device eliminates the need for hoses by connecting directly to pressure points, reducing refrigerant loss and streamlining measurements at remote locations.

• Wireless Mobility: 100m radio range for remote monitoring without physical connections. Eliminates hose usage, reducing refrigerant loss and measurement errors.
• Precision Measurement: Pressure range: -1 to 60 bar, suitable for low/high-pressure refrigeration systems. High-accuracy sensors for reliable readings in HVAC and refrigeration applications.
• Compact Design: Lightweight (156.6g) and portable (125×32×31mm) for one-handed operation. Direct pressure point connection for quick setup in tight or hard-to-reach areas.
• System Integration: Pairs with testo 115i to calculate refrigeration system parameters (e.g., superheat, subcooling). Compatible with Testo's wireless data logging ecosystem for comprehensive diagnostics.
• Operational Efficiency: Reduces service time by eliminating hose setup and refrigerant recharge needs. Real-time data transmission for immediate analysis during system trouble.
