At Duncan Instruments, we carry reliable models from leading manufacturers like AEMC, suitable for:

Verifying phase sequence in 3-phase electrical systems
Detecting live, missing, or reversed phases
Identifying proper motor rotation direction—contact or non-contact
Ensuring safety during generator and panel installations

Choose from CAT III and CAT IV-rated instruments, with models available for contact or non-contact operation, line-powered or battery-powered use, and CSA certification where applicable.
