Koehler Instrument Distributors - NEW Bench-Top Four Ball Tester

The K93170 Benchtop Four Ball Wear and EP Tester by Koehler Instrument Company, USA, sets a new standard for lubricant performance testing. Engineered for advanced tribological evaluation, this benchtop system determines the coefficient of friction, wear scar diameter, and load-carrying capacity of lubricants under controlled speed, temperature, and load conditions.

Built to perform both Wear Preventive (WP) and Extreme Pressure (EP) tests, the K93170 allows precise control over all test parameters through its integrated 15-inch multi-touch display, providing intuitive operation and real-time data visualization.

The system features a built-in pneumatic loading mechanism (up to 1000 kg) for consistent and accurate load application, ensuring full compliance with ASTM D2266, D4172, D5183, D2596, and D2783 test protocols.

Its compact benchtop footprint (62.5 × 50 × 90 cm) makes it ideal for laboratories with limited space, while the integrated pneumatic moisture control system guarantees reliable performance in variable environmental conditions.

With predefined ASTM standard methods and custom user-defined test sequences, the K93170 enables both routine quality control and advanced R&D investigations into lubricant behavior under high-stress mechanical contact.
