Smart Probe Kit - HVAC/R Test & Load Set for Air Conditioning, Refrigeration & Heating System - with 2X 115i Clamp Meter, 2X 549i High Pressure Gauge, 2X 605i Thermohygrometer – with Bluetooth

HVAC TESTOED DAD APPROVED!!! These are a beast. Much more durable than my last ones I love the plastic gaskets. It seals better than the rubber ones. Connects to mini-split adapters and to units easly. Very spot on accuracy and can be zeroed out. Easy to use and connecting the app and all the functions are awesome. I work HVAC industry and these work awesome!!!

As a HVAC technician I have used analog, digital, and now wireless probes. The Testo Smart Probe Kit works absolutely fantastic. Works great with the testo app on iphone, pairing is a breeze. These probes have great range, feel durable in your hands and make diagnosing and testing much easier. My favorite part about the Testo probe set is that it cuts out taking refrigerant out of a system when you gauge up and risking contamination. Quality built product!

Love this kit! Testo best out there!

Like the probes but I wish testo made their fittings low loss. Makes for some frozen fingers at times.

When I first placed my order, my set came without 2 of the 605i’s. Got in contact with Amazon and they corrected the issue. In few days time, the probes reached my home. I tested the probes out on my home’s ac and it’s easy to use. Downloading the smart probe app is a breeze. Move over 557, the smart probes are my go to. Love them so much, I ended up getting the rest of the probes. I didn’t have a problem losing connectivity from different sites. I recommend them to everyone.

I have been a big fan of Testo for over 10 years and that’s why I bought these.Very disappointed in the quality and design.Very cheaply made.They don’t have the features of the Fieldpiece meaning a led you can see in the sunlight,no warning if the temperature probes lose contact,better software,ect.ect.ect.The temperature clamp spring is to loose and won’t clamp on 1/4” or 3/8” on a vertical pipe without falling half off not to mention how slow the temperature clamps are compared to the Fieldpiece clamps.The fieldpiece is set is more expensive,but worth it.I have never been a fan of fieldpiece,but they have a home run with their smart probes.I still prefer Testo’s manifold over the fieldpiece manifold and hope they can make some improvements to their smart probes to be more competitive in the future.Until then I will continue to use the best product regardless of cost.

Downloaded the app, switched on the devices and connected to lines. Data came right up in app. Display made sense and i found it useful. I would recommend to anyone in the industry. The LED on the on switch on each device is not that bright and its hard to see if it is on or off. Also they could have used quick disconnect fittings on the pressure sensors, considering the money they are charging. And on the Low side a Quick disconnect with a service Tee so we can sense and charge at the sane time. Came in nice case with retention straps and separate attached document bag.

I have used this set for a month or two now and have nothing but great things to say. This kit is great for displaying information to customers as well as being able to diagnose issues with the all the information the kit provides.

Fácil de usar y la información que se despliega en la aplicación es muy completa y fácil de interpretar. permite además conectar sondas adicionales que refuerzan las mediciones.
