The IET Labs Inc HACS-Z-A-6E-1PF-BNC is a precision decade capacitance standard engineered for high-accuracy capacitance measurements and calibration across demanding laboratory environments. This 3-terminal, double-shielded instrument delivers capacitance values from 1 pF to 11,111 µF with 1 pF resolution and ±(0.05% + 0.5 pF) accuracy at 1 kHz up to 1,000 µF. The design employs trimmable air capacitors for lowest decades, sealed India ruby mica capacitors for mid-range stability, and metalized polyphenylene sulfide capacitors for higher decades.
