Your cart is empty.The testo 549i Smart Probe is a hose-less, wire-less, pressure probe for measuring refrigerant charge in AC/Refrigeration systems. It is used for servicing, troubleshooting, and documenting the operation of residential or commercial AC/refrigeration systems. When two 549i are used in conjunction with two 115i pipe-clamp temperature probes it is easy to monitor superheat and sub-cooling in AC/refrigeration systems. Users can read the measurements using the testo Smart Probes App installed on their smart device. The testo 549i easily connects to standard Schrader valves without tools and without hoses, eliminating any refrigerant loss. The testo 549i works on smart devices with either Android or Apple operating systems at distances up to 350'.

This is the perfect companion to the Testo Vacuum gauge. For HVAC (Minisplit) high pressure test, this is GREAT and worked well on a 600PSI nitrogen test I just ran last week. It uses iPhone for display and pairs with bluetooth. The only ding I can say is the APP is a little confusing at first, and doesn't respond until there is pressure detected, then it springs to life and starts measuring.LOVE THIS. And the companion Vacuum that looks exactly the same. Essential for Minisplit DIY if you want to test your lines properly. This saves $ over the all-in-one gauges from CPS and others.

No need to bring gauges just to check pressures

Be careful if ordering this for work, it may not deliver in one day. Mine took 4 days with Prime. Amazon said it's a "third party seller" well then don't false advertise. The probes work great no issues with the product itself.

The Testo High Pressure Gauges (and Vacuum Gauge) are vital tools in an HVAC kit.I recently installed a mini-split and wanted to test out the pressure after hooking everything up. I had decided on the Testo platform and already had their Digital Manifold, so I added in the wireless probles.These connect very easily to the system, though I do recommend using them alongside with a core removal tool or core depressor so you can easily isolate and disconnect them. This is to avoid releasing that short burst of refrigerant, especially from the high side when connecting. I mostly using Appion tools for the removal / depressor tools.For traditional systems, these will just connect right up to the high / low side ports. If you are connecting to a mini-split, you'll likely need a 5/16" adapter. Though I dont think Testo makes sense, they are readily available and I have a few different brands that I keep in the kit.I'm very happy with the testo tools, and that you can save all the data to the App for future review. Since these don't need to be connected with hoses, if you dont want to, you are also potentially losing less refrigerant when using them.When combining these with the wireless temperature clamps, the app will automatically calculate subcool / superheat so you can properly review and charge the system accordingly. This definitely beats the manual method. Even though these do cost more to make a complete kit, I would take this over a manual gauge any day for its accuracy and other features.

This is fantastic, except that the valve depressor is longer than needed, and so it can take a second to get it unscrewed to where refrigerant is not escaping. This is a huge waste of refrigerant, and defeats part of the advantage of this tool. If you use it along with this (http://amazon.com/dp/B085VZGJBF or similar) depressor, you can eliminate all the waste, and then the tool is back to fantastic.

These are easy to setup and use. This is the only review I have ever written and the reason for it is the intuitive interface and the overall ruggedness of the probes. I just replaced my original (non 45° fittings) smart probes with these newer gen versions (NOT because the old ones don't work!!) I am the maintenance supervisor for a 200 unit apartment complex and I wanted the ability to work on and/or multiple systems. Worth EVERY penny!!
