The Checkline CTM2 Digital Cable Tension Meter quickly measures tension in guy wires, zip lines, guardrail cables, and utility lines. It installs, measures, and removes in seconds. The CTM2 features a precision loadcell for highly accurate measurements that do not require lookup or correction tables.

The CTM2 can be placed on a cable, measure the tension, and removed in under three seconds! There are no complex lookup tables, and no conversion charts. The operator can quickly select from 20 different wire sizes and types stored in CTM2's memory. The Check-Tensioning mode graphically displays the current and target tensions for an extremely quick setting of line tension. Even the infrequent battery changes are quick.

The CTM2 is used in many industries to ensure proper tensioning. Typical applications include tower and stack guy wires, zip lines, pretensioned cable barriers, bridges, elevators, winch rope, overhead electric transit wires, fall arrest systems, hll horizontal life lines, aircraft cables, and utilities.
