Tension Meter CTM

2 Tension ranges available
up to 10 kN and 45 kN

For ropes up to Ø 25,4 mm (1 inch)

Electronic wire rope tension meter to determine the tension of pretensioned, non-moving ropes, wires, overhead lines, guy wires, cables, zip lines, guardrail cables etc. up to max. Ø 25.4 mm (1 inch).

Battery operated hand-held tension meter tension meter for quick measurements with a large easy to read LCD display

CE mark

Special Features

Rigid, portable tension meter CTM for rope diameters from 4.75 up to 25.4 mm (3/16 up to 1 inch), designed for outdoor use

The reading is shown directly in the display; their is no need for comparison tables

Large, easy to read, backlighted LCD display; digit hight 2.54 cm

User selectable units kN, lbf, kgf

Delivery includes calibration for one material. Calibrations for total 20 different materials can be made and saved.

The instrument is supplied with one set of sheaves (rollers). Three sheave sizes are available. For most applications one sheave set for the entire assortment of wire they tension will be sufficient.  The operator must use the appropriate sheave set for the wire size and calibration stored. Changing sheaves sets can be done quickly.

A extended long handle engages meter quickly with minimal effort

The readings can be stored  and later transferred using the RS-232 interface to PC

Standard Features

Easy to operate – force sensor and display are integrated in the same housing

Battery operation (AA)

CE approved (tested for electromagnetic compatibility)

Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Specifications subject to change without notice!

We have a large selection of calibration samples. Please inform us about your wire diameter and construction to check if we can use or samples or if you must send us  a sample. In this case you must send us 5 m of  the material to be measured, if our standard samples differ from your material.
To get the highest accuracy for various cable constructions with the same diameter (e. g. Ø 6 mm 7×7 and Ø 6 mm 6×19), different calibrations should be used.
