Triplett CM3000-NIST 1000A TRMS AC/DC Clamp with 3000A AC Flex Clamp with Dual Type K and µA with Certificate of Traceability to N.I.S.T.
- True RMS provides better accuracy when measuring non-sinusoidal or noisy waveforms
- Captures the instantaneous surge (inrush) current when power equipment is turned on
- 1.7” (42mm) clamp jaw
- Built-in Non-Contact Voltage Detector with audible/visual alerts
- Low Pass Filter (LPF) for filtering frequency and harmonic interference when measuring variable frequency drives

The Triplett CM3000-NIST is a versatile and highly capable clamp meter designed for precise electrical measurements. It can measure AC/DC current up to 1000A without the need to break the circuit by clamping around a single conductor, saving time and preventing circuit damage. Additionally, it includes a 3000A AC Flex Clamp for measuring high current (1.5 to 3000A) in tight spaces. True RMS technology ensures accurate measurements even for non-sinusoidal or noisy waveforms.
The Triplett CM3000 Clamp Meter is a reliable and versatile tool for professionals and technicians in various electrical and electronic fields. It offers advanced features and comprehensive accessories to simplify electrical measurements and enhance safety.
CM3000-NIST comes with Certificate of Traceability to N.I.S.T.
