Show original supplier description
The Rotary Compression Tester RCTV5.2 is a digital diagnostic tool engineered for Wankel Rotary engines, from classic 10A models to the modern Renesis 13B. It is built with the latest ARM Cortex M4 Microcontrollers, ensuring maximum performance, high resolution, and low power consumption. This unit provides accurate, reliable, and repeatable compression readings across all rotary engines, including those modified for over 1000HP drag racing applications. It is compatible with all oil and fuel types. A custom billet pressure sensor, developed over 12 months of R&D, is specifically designed for rotary engines, eliminating the need for adapters and reducing dead volume. The RCTV5.2 unit corrects for RPM and elevation, displaying results in PSI, Kg/2, Bar, and kPa. The tester is a plug-and-play design with proprietary electronics, firmware, and sensor, allowing for multi-chamber compression tests for both DIY enthusiasts and professionals. Included with the tester are the 5.2 Tester and Billet sensor, a protective silicone boot, a shock-proof storage case, a 3ft extension cable, a cleaning towel, a 9v Duracell battery, extra O-rings, and a decal. The product comes with a manufacturer's limited warranty and free shipping.
