Wireless Refrigeration Pressure Measurement for HVAC Engineers
The Testo 549i Smart Probe High-Pressure Gauge is designed for HVAC engineers, refrigeration technicians and air conditioning installers who need a fast and efficient way to measure system pressures during servicing, commissioning and fault finding. Operating wirelessly with the Testo Smart App, the 549i enables accurate high and low-pressure measurements without the need for traditional hoses, helping to minimise refrigerant loss and improve efficiency.
Designed for Modern Refrigeration and Air Conditioning Systems
The compact 549i connects directly to the pressure service port and transmits readings via Bluetooth to a smartphone or tablet. With a wireless range of up to 100 metres, engineers can monitor readings from a safe and convenient location. When used alongside the Testo 115i Clamp Thermometer, the system can automatically calculate superheat and subcooling values, making refrigeration system diagnostics quicker and easier. Measurement reports can be generated and exported directly as PDF or Excel files using the Testo Smart App.
