Coralba Roads Products

There is always a Coralba instrument suitable for your application and budget. All instruments have been designed for 24-hour use and easy installation. The distinct buttons are internally illuminated to indicate which function has been selected. The housing is made of strong aluminium profile to protect the electronics in extreme temperatures and physical environments.

    Coralba Mini/t

    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.


    Functions:
    Distance 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.
    Speed
    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.


    Technical specification:
    Power: 12 volt (24 volt optional)
    Size: 78 x 45 x 52 mm
    Weight: 180 grams
    Shock: 100 G
    Operating temp.: -25°C to +85°C

  • Coralba Trip - most popular tripmeter

    Coralba Trip
    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).

    Functions:
    Distance
    There are three very precise tripmeters, which can be set to measure distance separately in different directions. It is easy to freeze, halt, preset a value or correct it even without stopping the car. The instrument uses a patented method to measure the centre of a junction from a moving vehicle. The tripmeter automatically switches direction when the car is travelling in reverse.
    Speed A precision speedometer shows the actual speed of your vehicle, as well as average and maximum speed. There is also an optional speed threshold that warns the user should they exceed a certain speed.
    Automatic journey measurement This is a very easy way to monitor the total distance and time for an assignment. The instrument starts automatically when the car moves. At the end of the job the split function shows distance, time, average and maximum speed.
    Temperature If the instrument is connected to an optional sensor it can show the outside temperature with a precision down to one decimal
    Unit Counting The instrument is equipped with a register to count number of any kind of items, such as lamp columns, gullies, potholes etc.
    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.
    Measurements The instrument can be set to measure different units for distance and speed.

    Coralba Trip/3

    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.

    Functions:
    Distance There are three very precise tripmeters, which can be set to measure distance separately in different directions. It is easy to freeze, halt, preset a value or correct it even without stopping the car. The instrument uses a patented method to measure the centre of a junction from a moving vehicle. The tripmeter automatically switches direction when the car is travelling in reverse.

  • Coralba µ - tripmeter for winter countries

    Coralba µ

    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.

    Functions:
    Distance
    There are three very precise tripmeters, which can be set to measure distance separately in different directions. It is easy to freeze, halt, preset a value or correct it even without stopping the car. The instrument uses a patented method to measure the centre of a junction from a moving vehicle. The tripmeter automatically switches direction when the car is travelling in reverse.
    Friction testing A friction coefficient is determined by measuring how quickly the car decelerates using its braking system. A corrected value is also calculated adjusting for wind resistance and up/down hill effect.
    Speed A precision speedometer shows the actual speed of your vehicle, as well as average and maximum speed. There is also an optional speed threshold that warns the user should they exceed a certain speed.
    Automatic journey measurement This is a very easy way to monitor the total distance and time for an assignment. The instrument starts automatically when the car moves. At the end of the job the split function shows distance, time, average and maximum speed.

    Coralba µ/3

    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.

    Functions:
