UEi HUB is the companion app for all HUB test kits. Enable Bluetooth on your mobile device to read tool values from your HUB probes (WOT2, WPC1, WPC2, WPP1, WHP1, WVG2). In addition to measurement values HUB calculates and displays important refrigerant side, air side and vacuum parameters all in your preferred units. Monitor Superheat and Subcooling for any of the included refrigerants. Add refrigerants to your favorites list to quickly change between them on the refrigerant side display. Smoothly transition between vacuum, refrigerant side or air side values with a swipe of the display. With the simple drag and drop connection process, and ample wireless range HUB makes it easy to get the system information you need without being tied to a fixed location on the job site.
