Review on 🌡️ Enhanced Testo 550S Manifold Thermometer: Efficient Testing, Measuring & Inspection by Raymond Iglesias

Little time in the field but still impressive. appears to be a solid, well-built device. Exactly the same set as in the store, but much cheaper. Literally hundreds of dollars cheaper. The Bluetooth connection is clumsy. Your phone should connect automatically if it's in range and the app is activated. Sometimes it takes too long to connect. Sometimes it just won't connect at all, a way to manually connect to the phone would make it better. I still don't understand how exactly the evacuation function works. I'm not sure if this requires an evacuation sensor. The reporting feature in the app is great. Entering customer information is a little awkward, but as an accounting nut it's extremely useful.
