Bluetooth HHP App Details

As the library of wire rope diameters and constructions is increased each app user will benefit when they update and receive any new data.

A useful data-logging feature within the app allows the operator to log changes in tension v time and date if required; this data can then be emailed or uploaded to the cloud straight from the smart device in use.

Constructed from aerospace grade aluminium the COLT digital tensionmeter 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 smart device holder allows the COLT to be used as a traditional tension meter with on board display or the smartphone maybe 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.
