Calibrating cable tie tools is necessary to ensure that the tension settings on the tool remain accurate. 

JLW Instruments will calibrate the cable tie tool for $50 (quantity discounts are available). With a calibration you will receive a certificate detailing what the tension value was before calibration and after calibration.

JLW instruments service department has been A2LA accredited (certificate #1753.01) since 2001. Besides calibrating Hellerman cable tie tools we also calibrate force, torque, and pressure instruments. We also calibrate strength analysis equipment.

If a repair is required please contact the manufacturer. JLW Instruments will perform calibrations but we do not do the repairs on this equipment.
