What We Repair

Every instrument we service is treated as a critical asset. Our repair and calibration work is precise, documented, and held to the standards your industry requires.

01

Multimeter Repair

When measurement accuracy is non-negotiable, we restore digital and analog multimeters to NIST-traceable calibration standards. All major brands. Full diagnostic documentation included.

02

Relay Test Set Repairs

Relay test sets are essential for verifying protective relay operation in substations and industrial facilities. We diagnose and repair current and voltage output faults, timing circuit failures, and communication interface issues — restoring your test set to full operational accuracy.

03

Power Analyzer Servicing

Single and three-phase power analyzers are the backbone of load monitoring. We restore measurement accuracy and recalibrate to spec, keeping your critical systems in check.

04

Electrical Safety Tester Repair

PAT testers, hipot testers, and ground bond testers carry compliance weight. We return them to full operational spec and provide documentation to support your audit trail.

05

Custom Diagnostic Equipment

Proprietary and custom-built instruments deserve the same precision as off-the-shelf gear. We partner with your engineering team to understand, diagnose, and restore what others won't touch.
