Spot Friction Measurement Device
The portable TES Mk 3 Electronic Decelerometer is designed for simplicity of installation and operation. The capabilities and operational ease of the device surpass those of any other portable meter on the market.
Originally developed for Transport Canada, this latest generation of TES Instruments friction devices is approved by TC for use in Canada and by the FAA for use in the USA.
Utilizing the latest high-speed microprocessor technology, low power consumption, a wide operating temperature range and a built-in self-test feature, accurate results and high reliability are achieved.
