The Testo 552 Bluetooth vacuum gauge is a digital micron gauge, ideal 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.
Precise deep vacuum measurements, measuring down to single digit resolutions use optimized Pirani sensors. The resolution depends on the number of microns:
The testo 552 has real time calculations for the saturation temperature of water, which determines the proper micron/temperature levels at which moisture is removed from the system. These internal calculations inform you when/if the pressure is low enough to meet your evacuation target. This saves time and provides you with the assurance that the system is now free from moisture and contaminants. User defined alarm points alert you when target values are reached.
The new testo 552 with Bluetooth links to your smart phone or device. It also 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.
