Precise deep vacuum measurements, measuring down to single digit resolutions, are done with Pirani sensors. 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. 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.
