The Straightpoint COLT is a lightweight wire rope 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.

Constructed from aerospace grade aluminum 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 on board display or the smartphone can be handheld or mounted elsewhere.

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

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

Features and benefits:

  • Unlimited wire rope calibration database via Android or iOS app.
  • Main swivel joints fitted with high quality bearings.
  • Lever ratio of 5.3:1 allows effortless, safe, clamping onto pre-tensioned wire ropes.
  • Wireless Bluetooth 4.1 enabling operator to stand at safe distance up to 328 feet or 100 metres.
  • Quick intuitive adjustable centre sheave makes changing wire rope sizes fast and easy.
  • No easily broken external antennae.
  • High waterproof resistant design IP67 or NEMA6 for all weather use
  • Massive battery life of 1000 hours operational time.
  • As the library of wire rope diameters and constructions is increased each app user will benefit when they update and receive any new data.
  • Cable gauge included.
