GENRAD 1689 IET LABS

Precision Impedance Meter GenRad 1689 IET Labs

Advanced Instrument for High-Accuracy Impedance Measurements

The GenRad 1689 Precision Impedance Meter from IET Labs is a benchmark instrument for measuring AC resistance, low-frequency inductance, and capacitance with exceptional accuracy. Trusted by professionals in metrology labs, production lines, and design facilities, this device delivers consistent, high-precision results across a wide range of impedance testing applications.

It features a programmable frequency range from 12 Hz to 100 kHz, making it suitable for component evaluation, quality control, and dielectric measurements. The unit achieves 0.02% accuracy for impedance values and a dissipation factor (Df) precision of ±0.0001, setting the standard for critical RLC measurements.

The intuitive LED display shows 5-digit RLC values and 4-digit D/Q values simultaneously. Built-in automated features such as parameter selection, auto-zeroing, and limit comparison functions ensure high throughput and minimal operator error. The GenRad 1689 also supports advanced remote control via optional IEEE-488.2 GPIB interface for seamless integration into automated test setups.
