Special Price 26043

Regular Price: 28647.00


The Testo 552 Digital Vacuum/Micron Gauge is the ideal instrument for monitoring the evacuation of air conditioning, refrigeration, and heat pump systems. It is rich in features that make your work faster, easier, and more accurate.


Product Description

The new testo 552 with Bluetooth links to your smart phone or device. The testo 552 uses the free testo SMART Probes App which is a powerful and easy-to-use tool. It allows you to remotely read measurements of 1 to 6 Smart Probes including the testo 552. You can easily document / report the results.

It is one of the most accurate vacuum gauge for servicing air conditioning and refrigeration equipment on the market today.

Evacuating is a process of both degassing and dehydrating. Of particular interest to those working on refrigeration systems where the box temperature may not be above freezing when servicing is an indication of the saturation temperature of water for the level of vacuum that is being obtained. Comparing the saturation temperature of H2O to that of the box temperature will allow the technician to determine if moisture could be present and or if ice has formed and is sublimating in the refrigerant system, increasing vapor pressure and otherwise indicating what might appear to be a leak. Moisture and or ice in A/C refrigeration systems can cause significant problems leading to catastrophic failure. Trust the Testo 552 to be right.
