The Check-Line CTM2 Digital Cable Tension Meter quickly measures tension in guy wires, zip lines, guardrail cable 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 its tension, and removed in under three seconds! There are no complex lookup tables, 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 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.

Calibration Suggested wire calibrations:
Calibrate each cable diameter installed with the most appropriate sheaves. If two cable types are used of the same diameter (e.g. ½” 7x7 and ½” 6x19), calibrate each type independently if accuracy is critical.
Recalibration: At user discretion. Commonly 24 months but should be more frequently with heavy use. Factory recalibration conducted typically in 2-4 days.
Custom Calibration Available
The CTM2 can be calibrated with a customer supplied sample if none of the factory calibrated materials are suitable. In this case a 10 ft. sample must be supplied (non-returnable).
