A grounding system you cannot measure is a safety assumption, not a verified fact. Insulation does not fail all at once, it degrades, and the reading that catches it early is the difference between planned maintenance and an unplanned outage. Electrical safety and reliability rest on measurements that have to be right.
AEMC Instruments builds the instruments that make those measurements, and the line is now available through AV-TEK Consulting, with NIST-traceable calibration and application support across North America.
AEMC Instruments is a manufacturer of electrical test and measurement equipment for ground and insulation testing, current and power measurement, and data logging. AEMC Instruments are used by maintenance and reliability teams, utilities, QA departments, and laboratories that need defensible electrical measurements in the field and on the bench.
Available today through AV-TEK: ground resistance testers, including clamp-on and multifunction models; megohmmeters and insulation resistance testers; micro-ohmmeters for low-resistance and bonding checks; digital transformer ratiometers; clamp-on AC current probes; power and energy loggers and power quality analyzers; cable verification and tracing analyzers; and non-contact high voltage detectors. Many models include Bluetooth and AEMC DataView software for logging and reporting.
Utilities and substations for ground grid testing and transformer ratio checks, industrial maintenance and reliability, data centers and critical facilities for grounding and power quality, electrical contractors, and testing laboratories and manufacturing QA. Wherever electrical safety and performance have to be proven with a number, these are the instruments that produce it.
Ground and insulation testing catch faults before they become failures or hazards, not after. Clamp-on ground resistance testers measure without disconnecting the electrode, so routine checks do not require downtime. Data logging and DataView turn spot checks into records for compliance, trending, and audits.
AEMC Instruments are available for direct online purchase through AV-TEK Consulting, with pricing shown on each product page. AV-TEK adds technical selection, application support, and NIST-traceable calibration and repair, so the instrument you buy stays traceable through its service life.

Yes. AV-TEK offers NIST-traceable calibration and repair support. Contact us to schedule calibration for a new or existing instrument.
A clamp-on tester measures ground loop resistance without disconnecting the electrode, which is fast for routine checks. A multifunction tester supports fall-of-potential and other methods for commissioning and detailed diagnostics. AV-TEK can match the method to your application.
Many models include Bluetooth and AEMC DataView software for data logging, reporting, and trending.
