Greetings all. Today we’re going to take a look at the new and improved Testo 550 Digital Manifold with Bluetooth that retains the excellent features of the old version 550 but now includes wireless connectivity and comes at a reduced price. This new version of the 550 is a great deal for customers that want to get into digital manifolds and improves upon the old model in nearly every way.

Summer is in full bore and there is no better time to discuss Testo’s 550  Refrigerant System Analyzers. These analyzers are a great upgrade for any technician who is not currently using a RSA.

First off, this unit is preprogrammed for 34 refrigerants instead of the 3 gasses most manifold gauges are calibrated for.  This gives you a lot of relief of not having the right tool for the job. Another benefit of the Testo 550 Refrigerant System Analyzer is that all the information is displayed on a single screen.
