The UNI-T UT210B is a compact True RMS clamp meter for non-contact AC current measurement up to 200A. Its narrow jaw, NCV detection and MAX/MIN functions make it suitable for electrical maintenance and measurements in confined spaces.
Key Features
- True RMS measurement provides reliable AC current readings on both sinusoidal and non-sinusoidal signals.
- Measures AC current across 2A, 20A and 200A ranges without disconnecting the conductor.
- Compact body and approximately 16mm jaw opening provide easier access to conductors in confined panels and crowded wiring.
- Integrated NCV function enables non-contact detection of nearby AC electric fields.
- MAX/MIN, relative and Data Hold functions are supported by a 2000-count backlit display and automatic power-off.
