Ohmmeters for Every Application – Precision You Can Trust

Duncan Instruments was founded in 1968 when Matt Duncan began importing high-quality Cropico ohmmeters from Scotland. That legacy of precision and trust continues today with one of Canada’s widest selections of ohmmeters — from rugged micro-ohmmeters and high-voltage insulation testers to compact meters for everyday field use.

We do more than just sell instruments — we service and calibrate hundreds of ohmmeters each year in-house, helping ensure accuracy and long-term reliability.

Explore industry-trusted brands like AEMC, Metrel, Megabras, and more. All products ship quickly from our Ontario facility and are backed by expert advice and decades of experience.
