New digital manifold range from Testo

Testo are excited to be introducing a whole new range of digital manifolds for the installation and servicing of refrigeration systems, air-conditioning, and heat pumps.

This new generation of manifolds offer a robust design with weatherproofing to IP54 providing a reliable tool for outdoor use as well as a large graphic display which 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 complimented 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 as well as 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, helping you to carry out testing quicker and easier than ever before. Suitable for a range of applications on refrigeration, air conditioning systems and heat pumps.

Key models in the new range include:

• 550i – truly innovative 2-way ‘smart block’ manifold offering an entirely digital option
• 550 – 2 way manifold with large graphic display
• 557 – 4 way manifold with large graphic display

Product features include:

• Bluetooth wireless smart probes for temperature and vacuum with 100m range
• Pressure leak test function on testo 550s and 557s with graphical representation of values
• Live measurement and display of superheat/subcooling values
• IP54 protection class for reliable outdoor operation
