On-Road Friction and Distance Measurement Devices


Trippi designs and manufactures measurement instruments for road maintenance, construction, planning, and monitoring applications.

Solutions include precision trip (distance) meters, friction (slipperiness) meters, drive datalogging devices and other systems.

Distance measurement devices for the road industry

Trippi's distance measurement solutions are primarily based on actual distance driven with a vehicle, producing true driven distances and ensuring accurate measurements.

The n-series Eltrip-meters are dedicated, high-precision trip meters with optional reverse measurement capabilities. They can be very easily calibrated for each vehicle to ensure the highest possible measurement accuracy.

The Eltrip meters are available in a range of measurement resolutions to suit specific user requirements, varying from 10cm-10m resolutions for challenging scenarios.

Portable friction measurement solutions

The k-series Eltrip meters offer a reliable, repeatable and easily transportable measurement solution for slippery road surfaces involving ice, mud and sand (k standing for kitka, the Finnish word for friction).

Effective in higher latitudes, Eltrip-meters offer highly portable, compact and easy-to-use systems for performing both spot friction checks in any position, as well as control measurements in specific locations.

Friction measurement is easy to learn and highly repeatable, enabling clients to consistently have a clear, numeric friction value that indicates the current condition of the roads.

Clear friction readings can also help verify accident causes or localised hazards.

Specialised distance and payload measurement meters

Trippi offers customised research and development (R&D) services and solutions for a variety of special or unusual situations, including specialised distance datalogging services and payload stress determination in extremely heavy vehicles carrying potentially dangerous cargo.

Many Eltrip-meters can be found in places perhaps not initially expected, serving special user requirements, varying from bicycles and trains to heavy mining dump trucks.

Eltrip meters are both cost-effective and suitable for a wide range of applications.
