Testo 552 – Digital vacuum gauge with Bluetooth
The testo 552 is a high-precision digital vacuum gauge designed to provide the user with reliable readings. It has all the measuring functions need for evacuating refrigerant systems and heat pumps. It is built to last and tough enough to take the odd knock. It is extremely precise, rugged and practical – with visual alarm and backlit display.
Via a Bluetooth interface, the testo 552 connects with the testo Smart Probes App on the user’s smartphone or tablet. This allows monitoring the absolute pressure reached during the evacuation conveniently and wirelessly. In addition to this, the measurement results can be quickly documented in the App and sent by e-mail. And because the digital vacuum gauge is IP42 rated (water resistant and dirt-proof), it is virtually impervious to moisture and dirt.
