OEM Test & Measurement Instrument Sourcing China
1 resources tagged with "Test Measurement"
Test and measurement instruments from China — digital clamp meters, multimeters, and data loggers — hinge on measurement safety ratings, not just headline specs. A clamp meter rated True RMS for 1000A AC/DC needs CE plus UL/IEC 61010-1 certification, and the CAT rating (CAT III/CAT IV) determines whether it's safe on the circuit your customer will actually use it on. Bluetooth data logging is now common at the OEM level, but the safety certification is what a reseller is liable for if it's faked.
Sourcing test instruments means verifying the IEC 61010-1 safety listing and CAT rating are genuine — overstated CAT ratings on budget meters are a real safety and liability problem, so we check the certificate and the marked rating against the spec.

FAQ
What certification does a clamp meter need?
CE and UL/IEC 61010-1 for measurement equipment safety. The CAT rating (CAT III/IV) plus voltage limit must match the application, and the listing should be verifiable, not just printed on the case.
Does True RMS matter when sourcing clamp meters?
Yes for non-sinusoidal loads (motors, drives, electronics). True RMS reads those accurately while averaging meters don't. Confirm the True RMS claim is real, since some budget units mislabel it.
