CoMech are responsible for the sales, calibration and maintenance of all MiniProf profile measuring instruments for the UK and Ireland. The MiniProf units are becoming world-renowned with thousands of users in over 50 countries.

What are the MiniProf Units?

The MiniProf family from Greenwood Engineering includes the Rail, Wheel, Lightrail Wheel, Brake, Twinhead, Switch & Crossings and Wheel 400 measuring devices. Each unit features a full-contact, knife-shaped contact point for seamlessly cutting through layers of dirt, grease, frost and leaves, making them suitable for use in virtually any working environment.

Made from lightweight and ultra-strong titanium, the MiniProf units operate with a small magnetic measuring wheel and rotating high-resolution optical encoders. The combination of Bluetooth connectivity and professional Envision software gives the opportunity to wirelessly take a vast amount of measurements on Android smartphones, tablets and PCs, thus minimising risk while maximising efficiency.

Each new MiniProf device comes complete with a sturdy transport case that is waterproof, dustproof and impact resistant.

Key Features

Accuracy is ensured due to the full contact point on all instruments. An impressive 20-30.000 individual points are collected in one simple swoop of the magnetic wheel. In addition, these measurements are collected in less than five seconds with an accuracy range of 9-11µm. The great scope of measurement is made possible with the MiniProf Envision software, which is suitable for use with an Android smartphone, tablet or PC.

All the instruments have an operating temperature of -15°C to +35°C with a battery life of 10 hours or 1,000 Bluetooth measurements. This can be extended even further when they are connected via USB.

The MiniProf range has been specifically made for the quality control, maintenance and safety regulation of rail tracks, brakes and wheels. The easy to use instruments are perfect for using within rail depots and other places around the world.
