Calibration of Cable Tie Tools
$99 each


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 $99. With a calibration you will receive a certificate detailing what the tension value was before calibration and after calibration.

The tie tools we calibrate are the Hellerman EVO7, EVOSP, EVO9/EVO9SP, and EVO9HT.

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.
