Ultra-stable closed loop Fluxgate current transducers for applications requiring interference-resistant, parts-per-million accuracy from 12.5 to 1000A, galvanic insulation reinforced by an electrostatic shield across all models, with the ITN 12-P Ultrastab adding a metal housing for enhanced EMC immunity and a PCB-mount configuration for direct integration into measurement instruments. The ITN 12-P is the only model in the range designed for PCB mounting.

Applied in calibration laboratories, precision scientific instruments, medical environments, and any measurement system where current uncertainty must be expressed in parts per million and long-term stability under thermal and electrical interference is a requirement.
