Wireline Tension Meter from Straightpoint
The Crosby 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 free Android or iOS app.
Constructed from aerospace-grade aluminium, the COLT digital tensiometer is lightweight and easy to handle. Its main operational application is to be attached to wires/cables 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 it perfect to carry out on-site cable tension testing anywhere in the world.
An included calibration verification tool (CVT) allows the operator to self-check and verify calibration accuracy in the field, if required.
