Welcome to Commercial & Industrial Calibration

Who We Are
Commercial & Industrial Calibration is a fully mobile calibration service for electrical test equipment, working across the Illawarra and Sydney regions. Led by owner/operator Brad, who brings over 15 years' industry experience, we come to your site and calibrate multimeters, insulation resistance testers, PAT testers, clamp meters and more on the spot. No posting gear away, no waiting days for it to come back, and no juggling multiple providers for different equipment types.
What We Do
Many calibration services only handle certain equipment types, leaving you to split your gear across several providers. We calibrate multimeters, insulation resistance testers, PAT testers, clamp meters and multifunction installation testers from a single mobile setup, across the major brands your team already uses. One booking, one visit, one provider.
