【Product Overview】 The EHD Oil Film Thickness Tester is a tabletop fully automatic oil film thickness testing machine provided by PCS Instruments in the UK, and it is the successor model to the already proven EHD1. 【Features】 It is capable of measuring thinner films (minimum oil film thickness of 2nm) than conventional optical interference methods. By using the optional 3D-SLIM, it is possible to analyze the oil film thickness distribution across the entire contact area. 【Main Evaluation Contents】 Oil film thickness Stribeck curve (friction coefficient × rolling speed) Traction curve (friction coefficient × slip ratio) Oil film thickness distribution *Optional

【Product Overview】 The MPR Pitching Test Machine is a three-cylinder testing device provided by the UK company PCS Instruments, which generates pitching in a short time by increasing the contact cycles. 【Features】 Compared to general fatigue wear testing machines, it is compact and requires a smaller sample size for testing, making operation simple. In addition to stopping the test based on arbitrary parameters, it allows for interruption and resumption for surface observation of the test specimen. 【Main Evaluation Content】 Fatigue wear testing

【Product Overview】 The MTM Traction Tester is a tabletop friction and wear testing machine of the ball-on-disk type provided by PCS Instruments in the UK, and it is adopted as a standard device in the lubricants and additives industry. By optimizing friction characteristics, it significantly enhances performance and helps reduce operational costs. 【Features】 It is capable of sliding test specimens of various materials and shapes within a slip rate range of ±10,000%. By using the optional 3D-SLIM, it is possible to observe the formation process of the tribofilms. 【Main Evaluation Contents】 Stribeck curve (friction coefficient × rolling speed) Traction curve (friction coefficient × slip rate) Tribofilm measurement *Optional

**Product Overview** The ETM traction testing machine is a tabletop friction and wear testing machine of the ball-on-disk type, provided by the UK company PCS Instruments. It is specialized for testing conditions with higher surface pressures compared to the conventional MTM traction testing machine. **Features** It is capable of sliding test pieces within a slip rate range of ±10,000%. By using standard test pieces, it can reproduce surface pressures from 1.4 to 3.5 GPa, and in some materials, the maximum surface pressure can reach 7.1 GPa. By using the optional 3D-SLIM, it is possible to observe the process of tribofilm formation and removal. **Main Evaluation Contents** Stribeck curve (friction coefficient × rolling speed) Traction curve (friction coefficient × slip rate) Tribofilm measurement *Optional

**Product Overview** The USV high shear viscosity meter is a tabletop fully automatic rotational viscometer provided by PCS Instruments in the UK, designed to measure the viscosity of engine oil in conditions close to actual operation. **Features** It is capable of reproducing shear rates of 10^6 to 10^7/sec, which are observed in real engines. It can measure the complete temperature/shear rate distribution in approximately one hour. It enables accurate kinematic viscosity measurements in the high shear region, which is important in the automotive industry, and complies with domestic standards such as ASTM and CEC. **Main Evaluation Content** Shear rate distribution (viscosity × shear rate)
