Top 11 Best Digital Manifolds 2019

We are living in a technology-driven world and the ride seems smooth so far. In fact, the great technological revolution is changing the way of doing things.

And yes, Heating, Ventilation, and Air Conditioning (HVAC) industry has not been left behind, thanks to the invention of digital manifolds.

Initially, professionals in this industry relied on the analog manifold gauges to keep the functionality of the air conditioners and cooling devices at par.

However, just like any other analog technology, these traditional manifolds had their own shortcomings such as inaccuracy and the need to perform calculations on subcooling, superheat and pressure differentials.

Luckily, the introduction of digital manifolds has come as a real game changer. Digital manifolds offer great accuracy giving the technicians an easy time in vacuuming, testing, and recovering when dealing with heating and cooling systems.

Furthermore, unlike the old technology, the digital manifolds present output in digital format eliminating the need for calculations.

In this content, we saw it important to review the 11 market’s leading digital manifolds.

Let’s get started!
