TH0490 Bisector Current Ratio Standard

Electrical Calibration Standards

The TH0490 Bisectional Current Ratio Standard Series is engineered for precision broadband current measurement and calibration. It divides an input AC or DC current into two equal, phase-matched output channels with extremely small ratio deviation and phase displacement. The TH0490 is ideal for metrology institutes, R&D environments, calibration laboratories, and automated precision measurement systems requiring high accuracy up to 5kHz and 100kHz bandwidth versions.
