[testo 557BT Digital Manifold]
[testo 549 Digital Manifold]
Description
Testo 549 is a manifold that measures and displays refrigerant pressure in refrigeration systems and heat pumps. Compared to analog manifolds, there is no measurement error and no effect of vibration. Built-in temperature measurement and overheat/overcooling automatic calculation, no additional measurement or manual comparison required (when using optional temperature probe). It also supports 60 refrigerants including R32 refrigerants.

|---|---|---|---|
For measuring the pressure of refrigerant in refrigerant systemsTesto 549i is a smart probe with a built-in pressure sensor that can measure refrigerant pressure on a refrigerant system or heat pump.The main unit is small and portable, so you can check measurements with your smartphone or tablet.In addition, the condensation and evaporation temperature can be extracted from the refrigerant data in the dedicated app.Suitable for maintenance of refrigeration air conditioning systems. |
Entry Model Digital ManifoldTesto 549 is a metal heavy duty 2-way valve digital manifold with two pressure sensors (high pressure and low pressure side), two temperature sensors and three coolant hose holders.Easy to use and can be used in harsh environmental conditions. The 2-valve manifold is compatible with 60 refrigerants and has practical functions for smooth daily maintenance tasks. |
Bluetooth enabled digital manifoldThe testo 550BT 2-Way Manifold is suitable for maintenance of refrigeration air conditioning systems and heat pumps.In addition to measuring refrigerant pressure, pipe surface temperature and overcooling degree/overheating degree, as well as the condensation/evaporation temperature of the refrigerant. You can also use the app on your smartphone or tablet to view data remotely and document measurement data. |
Mobile compatible and vacuum measurements.The testo 557BT is a digital manifold that is convenient for the introduction and maintenance of refrigeration air conditioning systems and heat pumps.One unit acts as a manifold, thermometer, vacuum gauge and can also communicate with your smartphone or tablet via the app. When connected to the Pirani vacuum probe you can measure the precision of the vacuum and also work for airtight testing by sealing the vacuum on the frozen air conditioning systems and heat pumps. |
