QUALITY AND INNOVATION IN MOTOR TECHNOLOGY
- SINCE THE 1950S

Schleyer-Test-Equipment GmbH has been manufacturing globally recognized and robust test systems “Made in Germany” for combustion engines for decades. These systems offer maximum precision and reliability, ideal for professional users and hobby mechanics.

INNOVATION FOR THE WORKSHOP AND HOBBY:

Synchrometer and CO2 leak tester

With the SK or BK synchrometer, car mechanics, car restorers and hobbyists can quickly and easily check and adjust the exact air flow rate of the carburetor without dismantling the carburetor. The CO2 leak tester is required for early and reliable detection of leaks between the combustion chamber and the cooling system.

FROM PIONEER TO GLOBAL BRAND:

The story of PHILIPP M. SCHLEYER

At the end of the 1950s, the inventor of the test device, Mr. Philipp M. Schleyer, founded the company “Schleyer Test Equipment”. Prior to this, Mr. Schleyer had been a globetrotter and hobbyist in America, where he dismantled an aircraft and had it sent to Germany in parts to be reassembled. Thanks to his many contacts all over the world, he was quickly able to make his test equipment known everywhere.
