The Testo 549i high-pressure gauge is a compact, smartphone-operated measuring instrument designed for efficient servicing and troubleshooting of air conditioning and refrigeration systems. Controlled via the Testo Smart App, it wirelessly measures both high and low pressure while offering automatic evaporation and condensation temperature calculations.
Because it connects directly to the pressure port without hoses, refrigerant loss is significantly reduced. Its long-range Bluetooth® connectivity (up to 100 m) makes it ideal for systems with widely spaced measuring points. When paired with the Testo 115i clamp thermometer, the 549i enables calculation of additional refrigeration parameters.
The Testo Smart App provides intuitive visualization of readings in graph or table format, supports multi-parameter analysis, and generates reports that can be sent directly as PDF or Excel files. Lightweight, robust, and highly mobile, the 549i is the ideal tool for modern HVAC/R technicians.
