Testometric's X100-COF: Friction Testing Machine

X100-COF is a dedicated friction testing model based on the X100-1 Universal Testing Machine and features complete computer control and a precision AC servo drive system. It has a friction slide and 200 g sled, compliant with many international standards such as ASTM D1894, BS EN ISO 8259 and TAPPI T549. 

Thanks to the universal modular design, the X100-COF can be easily modified for other test types such as compression and tensile testing using Testometric’s wide range of fixtures and grips.

Optional Tablet PC

Upon pairing X100-COF with a TPC1 tablet PC that is optional, it becomes a robust independent system without the necessity of a laptop or external PC. The TPC1 tablet PC has touchscreen control and utilizes a dedicated version WinTest software that is enhanced for touchscreen operation.

The Tablet PC offers a fully-featured test environment with the capability to create and store limitless methods and results. Users can adjust to an ergonomic working position since the height, reach and viewing angle of the mounting arm that attaches to the machine column T-slots can be adjusted. The machine can also be connected to a laptop or conventional desktop PC using the WinTest EC software.

Tried and Tested Software

Each Testometric model is supplied with an inclusive WinTest Analysis software package. The WinTest Analysis includes many years of development and thus provides an easy and intuitive software package that suits material testing of all kinds. The integrated test methods offer tensile, flexural, compression, peel, shear, tear, cyclic, creep and multi-stage tests.

A broad range of facilities and industry-standard test methods are available to build and store many test methods. All test data can be automatically stored and can be exported to other software packages such as word, excel, access and SPC systems for further interpretation.

The WinTest software datasheet can be used to get a better understanding of the features. The inclusion of the RCE remote connection facility in all machines can be web-linked directly to Testometric for monitoring, remote investigation and software upgrades. The RCE datasheet can be used for further information.
