Testo 549i

High-Pressure Gauge

Part/Code: TES0560-254902

Testo 549i - High-pressure gauge operated via smartphone

Product Description:

Testo offers you greater mobility when measuring: used in conjunction with your smartphone or tablet, the handy testo 549i high-pressure gauge is suitable for carrying out wireless servicing and troubleshooting on air conditioning and refrigeration systems, as well as for installing them. The measuring instrument can be quickly and easily attached directly to the pressure connection. The testo 549i makes it considerably easier to work on pressure connections that are a long distance apart, thanks to wireless connection to a smartphone or tablet.

Also practical: since no hoses are needed for the measurements, no refrigerant is lost, or only a very small quantity. When used in conjunction with the testo 115i clamp thermometer, individual refrigeration system parameters can also be calculated.

Features & Benefits:

• Measurement of high and low pressure
• Low refrigerant loss – since no hoses are required for measurements
