If you only occasionally need to measure accurate road lengths or distances, or for example only need to keep a very precise speed, then the Coralba Mini/t is perfect for you. It is built in the same way with the same reliability as the professional models. It is easy to install and use and the functions are a good balanced subset for the user with a low budget.


The Coralba Mini/t has two tripmeters, which can be used individually. It is simple to preset a value and to halt one of the tripmeters. The tripmeter also automatically switches direction when the car is travelling in reverse.


A precision speedometer shows the exact speed of your vehicle.

When the instrument is not in use it will automatically switch itself into an idling mode where the display and the keyboard are totally dark. When a button is pressed or the car starts moving it is automatically turned on again.

Distance units (e.g. feet, meters) are pre-set at the factory and cannot be altered by the user.



Power: 12 volt (24 volt optional)

Size: 78 x 45 x 52 mm

The Coralba Trip is the most popular Coralba instrument among road maintenance crews. It has all the functions necessary for road maintenance and management. The instrument measures distance, time, speed, quantity and temperature (optional).


The Coralba Trip/3 is the real professional work horse. It contains the same basic functions as a Coralba Trip. It also includes a lot of more sophisticated aid for the highway engineer. The three displays can be set independently of each other to show the selected functions. Two user defined remote controls may be connected. Even though the possibilities with Coralba Trip/3 are very comprehensive it is just as easy to use as a Coralba Trip.


The Coralba µ instrument has the same basic functions as the Coralba Trip as well as the features required to calculate the friction coefficient. Measuring friction is normally a time consuming and difficult task using very expensive equipment, but with the Coralba µ it can be accurately measured in a simple and safe way.


The Coralba µ/3 contains the same functions as a Coralba Trip/3. It is specially designed for winter road maintenance where the friction coefficient is displayed at the same time as other values. One possible use is to display distance, friction and temperature, which would give all the relevant information at the same time.
