Hellerman Calibration Tie Tools EVO

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

JLW Instruments will calibrate the Hellerman EVO7 and EVO9 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.
