ManTooth™ Wireless A/C Pressure/Temperature Gauge Automotive Kit for R-1234yf



The Yellow Jacket® ManTooth™ Wireless A/C Pressure/Temperature Gauge Automotive Kit use bluetooth technology and an app to provide service centers and technicians the ability to perform an accurate R-1234yf vehicle A/C system check in less than three minutes (on average). The automotive ManTooth kit utilizes a free downloadable app to calculate and display the system’s actual readings in an easy-to-read format on your iPhone, iPad, or Android device. Adding this to your current courtesy inspection or multi-point inspection process on every vehicle that rolls up to your shop is efficient and easy. It provides exact A/C system health status for your customer and maximizes that opportunity to up-sell additional A/C service.
