Testo has long been a popular brand in the HVACR industry – with a pretty extensive range of measurement tools. Last week, the company announced its newest range of manifolds, increasing the number of Bluetooth connected devices on offer.

The new tools are the 550s, the 557s, and the 550i. Starting with the cheapest unit, the 550i ($459) is a pretty basic 2-way manifold with no display. The idea here is that the tech relies entirely on their phone to view the measurements.

Next up is the 550s – this unit is also 2-way, but does include a decent-sized full graphical display. At $599 it is priced slightly higher than its main competitor, the Fieldpiece SMAN SM380V.

The top of the range unit is the new 4-way 557s. With its huge display, this unit is clearly the most impressive of the three. The package includes 2 wireless temperature probes, a vacuum probe, and a case. The 557s is available with or without hoses and

All three of the units are designed to support rugged outdoor use up to IP54. To learn more about these new manifolds and to find retailers, visit testo.com.
