Testo has introduced a new range of digital manifolds for the installation and servicing of refrigeration systems, air-conditioning, and heat pumps.

This new generation of manifolds offers a robust design with weatherproofing to IP54, providing a reliable tool for outdoor use and a large graphic display that allows all measurement parameters to be viewed on a single screen. With the ability to connect Bluetooth probes, the new range offers a wireless measurement solution and is complemented by a new multi-functional Smart App.

The large dot-matrix type LCD display of the testo 550 and 557 models can display all measurement values on a single screen allowing users to view all required values without scrolling between screens. Also, the display is capable of graphical representation of ‘analogue’ dials and digital values, allowing a simple transition for users who have previously used purely analogue gauge sets.

A range of Applications

The testo 550s and 557s give all values at a glance and is suitable for a range of applications on refrigeration, air conditioning systems and heat pumps.
