This high-precision digital vacuum gauge that has all the measuring functions you need for evacuating refrigerant systems and heat pumps. The rugged meter is built to last and tough enough to take the odd knock.
It can determine the proper micron/temperature level at which moisture is removed from the system with real time calculations determining the saturation temperature of water. These internal calculations are also used to inform you if and when the pressure is low enough to meet your evacuation target, thus saving you time and providing assurance that the system is now free from moisture and contaminants.
It is also the only vacuum gauge on the market with an absolute pressure sensor which is maintenance-free yet still able to provide you with 100% reliable readings.
Features
Applications
Evacuating is one of the most important steps when installing or restarting refrigerant or a/c systems: foreign gases, moisture and oils have to be removed properly. That's when the absolute pressure of a system needs to be measured.
The meter provides you with highly accurate information on the dehumidification status of the system and measures even the smallest of absolute pressures reliably. This means that you are always able to observe manufacturer specifications. A visual alarm warns immediately when a threshold has been exceeded.
Testo Smart Probes App
This vacuum gauge uses Bluetooth to link to your smart phone or device utilizing the free Testo SMART Probes App, which is a powerful and easy-to-use tool. This App allows you to remotely read measurements of 1 to 6 Testo Smart Probes including the 552, allowing you to easily document and report the results.

Complying with manufacturer's specifications
Some manufacturers specify exactly what the absolute pressure must be for you to evacuate your air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
Connect to the testo 570 Digital Manifold
When you connect the testo 552 Digital Vacuum Gauge to the testo 570 Digital Manifold, you can save the testo 552's readings directly on a laptop via the optional EasyKool software. This allows data-logging and/or on-site printing.
Complying with manufacturer's specifications
Some manufacturers specify the desired micron lower limit that must be achieved to evacuate their air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
Evacuating AC/R systems
The testo 552 Digital Vacuum Gauge is for the evacuation of heat pumps, air conditioning, and refrigeration systems. The innovative testo 552 utilizes a sensor that, unlike the competition, requires no cleaning and is not affected by contamination. Never worry about a dirty sensor causing false readings. Trust your testo 552 to always be accurate.
