  • Awesome Tool!
Worth every penny! I use this every single day! Get a charging tee and a ball valve hose and you can adjust the charge with these as well. The only thing that could make it better would be low loss/anti-blowback fittings from the factory. I added JB Industries low loss fittings and they are perfect. The APP is awesome as well! Super easy to set up and use. Highly recommend! ... show more

  • Good, but needs improvement
These gauges are good. They are easy to use and connect via Bluetooth The only issue I have with the gauges is the extreme loss of refrigerant when connecting the gauges. You absolutely must work fast to turn the knurled fitting, which happen to be small. I’m hoping to connect no loss fitting to minimize refrigerant loss and keep my fingers and palm from getting frostbite. ... show more

Review for Testo Smart Probe Kit I HVAC/R Gauge Set ~ Includes testo 115i and 549i. Wow what a great idea and I am upset not to have got this Bluetooth kit sooner. I travel for a living and this set is small, quick to connect and accurate. Battery life is great and easy to grab AAA is better than factory battery that would be hard to get quickly if failed. Testo you made several field engineers at a multi billion dollar firm very happy. Yes you can test oil, air, refrigerant, etc pressure and vac. ... show more

  • The future is now
I have been a tech for 15 years, and have had digital gauges during their infancy. This is a game changer, I can set these up on a compressor and walk away to another roof top unit to finish a PM job. Multi tasking at its finest! On the down side. The Testo App could use an overhaul, it could be more intuitive in my opinion. But still very useful once you get the hang of it ... show more
