StraightPoint COLT Calibration verification tool


COLT Calibration verification tool (CVT)

The Straightpoint COLT is a lightweight wire rope tension meter or shunt tension meter for fast and accurate measurement of tensions up to 11,000lb or 5000 kg and up to 1” or 25mm diameter.

Manufactured using an integral, high-accuracy, Bluetooth module the COLT transmits load data wirelessly to any smart device running our Android or iOS app.


The latest COLT App has two key modes, one for measuring tension on static wire rope lines and the other for the installation, repair and maintenance of elevator cars.

Wire Rope Mode:

  1. Records GPS coordinates
  2. Logs the local temperature and wind speed from the local NOAA
  3. Multi anchor data logging with camera mode for a photo on your report

Elevator Mode:

  1. Car weighing – measure tension on each cable and automatically calculate car weight
  2. Car balancing – measure and calculate the balance of load across up to 10 cables

Multiple drop tested from 3 metres or 10 feet.

Constructed from aerospace-grade aluminium the COLT digital tensiometer is lightweight and easy to handle and operates on wires that are already under tension. Once in place, it allows the operator to quickly check tension on cables or wire ropes set at any angle. A built-in magnetic smart device holder allows the COLT to be used as a traditional tension meter with an onboard display or the smartphone can be handheld or mounted elsewhere.

Supplied in a purpose-made carry case the COLT is portable and with standard alkaline batteries making this perfect for on-site cable tension measurement across the world.

The included calibration verification tool (CVT) allows the operator to self-check & verify calibration accuracy in the field if required.
