GenRad 1419 Series IET LABS

GenRad 1419 Series – IET Labs

Compact and Reliable Decade Capacitor for Precise Capacitance Substitution

The GenRad 1419 Series from IET Labs is a dependable line of capacitance substitution boxes designed for accurate and convenient capacitance settings in both laboratory and field environments. These units are ideal for simulating capacitors in test circuits, calibrating LCR meters, or serving as references in educational and R&D setups.

Available in three models—1419-A, 1419-B, and 1419-K—the 1419 Series offers a range of dial resolutions and dielectric materials to suit various precision and performance needs. Each model provides direct-reading decade capacitance with easy-to-operate rotary switches and clearly marked scales, ensuring user-friendly operation and dependable performance.

These capacitors use high-quality materials such as polystyrene and silvered mica for low dielectric absorption and high stability. The enclosures are shielded to minimize leakage and external interference, and the terminals are laid out for straightforward two-terminal measurements.
