SKU: UT208B Categories: ,


UT208B Clamp Meters are 42mm Jaw  6000-count digital clamp meters with auto-range, large LCD, true RMS, autoscale memory, and NCV functions.

They conform to CAT III 1000V/CAT IV 600V safety rating andcertified by CE/ETL. The UT206B, UT207B, and UT208B come with LoZ mode for eliminating ‘ghost ’voltage, LPF ACV function for measuring INV and VFD voltage, and inrush current mode for capturing transient current. The  UT208B also features high-precision temperature measurement with 0.1 °C resolution and can be equipped with a flexible current probe to extend the AC current measurement range to 3000A.
