Not ready for R-1234yf? Purchase the 37840 for R-134a today and we can update it to R-1234yf later with our optional (one time use) conversion kit.

To obtain pressure readings in a snap, each RMS unit comes with a YELLOW JACKET ManTooth™ Wireless Digital Pressure/Temperature Gauge so you can test the A/C system without losing refrigerant. The free downloadable app wirelessly calculates and displays the A/C system’s actual pressures in an easy-to-read color format on the RMS tablet, as well as iOS or Android™ devices.

Real-time remote support, including set-up/start-up assistance. With the system’s Window’s-based control tablet, we can remotely access your machine and provide training to show you how to use the machine and navigate the screens. All you need is a wireless connection. In addition, we can perform remote diagnostics, including using the tablet to take live video or photographs during the session if you need to show us something specific.
