Beckman Coulter 8211-R2K-L.5 Rotary Potentiometer

Beckman Coulter 8211-R2K-L.5 Rotary Potentiometer is a 2 kΩ rotary potentiometer used in Beckman Coulter instrumentation. As a variable resistor actuated by turning its shaft, it enables precise adjustment of signals within electronic circuits—useful for calibration of sensors, trimming analog paths, or tuning motor-control sections in laboratory analyzers. The 2 kΩ value indicates the track resistance across the potentiometer, a common range for compact, low-power control tasks in analytical instruments. This Beckman Coulter component helps technicians achieve stable, repeatable readings by allowing fine-tuning of gain or offset in analog signal chains, aligning instrument response with reference standards. When selecting spares or replacements, matching the 2 kΩ specification and the Beckman Coulter form factor is essential to ensure proper fit within instrument assemblies. Typically integrated on printed circuit boards or within modular instrument assemblies, these potentiometers withstand routine vibrational environments found in laboratory settings.
