Testo Digital Manifold 557s vs 558s

If you still haven't worked with or owned a digital manifold you are surely living in the dark and shooting yourself in the foot.

They are not only a relatively new technology but also a great helper in your HVAC daily work.

For example, Testo manufactures a list of different digital manifolds (see the photo below) but today let's look at some of the best in their historic line-up.

Let's talk a bit about the Testo 557s digital manifold now

This durable manifold comes with a four-way valve block which makes it simple and quick to measure heat pumps, air conditioners, and refrigeration systems. It has an intuitive large graphic display which you can control with the buttons or smartphone (Testo Smart app).

Here are some of the features:

• Fast and easy pressure value display in analog look
• Integrated calculation of the target superheat
• All results at a glance with the large graphic display
• Exceptionally compact and reliable thanks to the easy-to-handle, rugged housing with IP 54 protection class
• Easy, wireless measurement of vacuum and temperature via automatic Bluetooth® connection to the testo Smart Probes
• Refrigerant listing updates automatically using the App
• Even greater flexibility for your measurements and documentation with the testo Smart App
• Easy to use

 

Okay, let's switch to the brand new measuring device from Testo they released a short while ago...

Introducing the new Testo 558s

Easily, you can say that this is the smartest manifold ever offered.

Testo is transforming work on refrigeration, air conditioning and heat pump systems. Basically, when talking about HVAC this device will handle everything you throw at it easily and quickly.

One of the greatest new feature is the 3 ways how you can operate this manifold. First, the Testo 558s has a touchscreen, secondly it has manually operateable buttons (when you have working gloves on) and third - you can of course use the Testo Smart app on your smartphone.

It is even compatible with all flammable A3 and A2L refrigerants.

Fully networked allowing the 558s testo to work with many other testo measuring devices. For example, the Testo 558s works great with 115i temperature clamp, 552i vacuum probe, 560i refrigerant scale with valve, 770-3 clamp meter. You can even use the testo new 565i vacuum pump with the 558s.

Bluetooth range is up to 150m.

So, to sum it up, here are basically 5 reasons why to own a 558s digital manifold from Testo:

1. Automatic Bluetooth connection through auto-pairing
2. Protection class IP 54
3. Hybrid charging system consisting of rechargeable (USB-C) and non-rechargeable batteries
4. Connection to the testo Smart App for easy documentation and fast sending of measurement reports
5. High precision of 0.25 % fs over the entire measuring range (60 bar), including integrated temperature compensation

 

By the way, here's a quick release video by Testo of the new 558s digital manifold. They call it 'Genius', and we ain't denying that description. Watch the video below or on YouTube if you like.
