Mk 3 Electronic Decelerometer

The Mk 3 Electronic Decelerometer is a compact instrument for measuring and recording the maximum deceleration possible on a roadway or airport surface.

The Mk 3 is the latest and most sophisticated generation of TES Instruments’ coefficient of friction test devices, originally developed for Transport Canada (TC). The Mk 3 is approved for use in Canada by TC and in the USA by the FAA.



A built-in self test feature guarantees
reliable results and warns the
operator of detected malfunctions.


The unit can also be configured to control the switching of additional vehicle based systems such as ABS during friction testing.


Over 300 TES Electronic Decelerometers
are currently in service in Canada, the U.S. and Europe.
