Product Description

GESTRA LRG 16-4 Conductivity Electrode

The GESTRA LRG 16-4 is a conductivity electrode designed for level detection (minimum or maximum alarm) and conductivity monitoring in electrically conductive liquids. It is commonly used in steam boilers, condensate tanks, feedwater tanks, and other industrial applications requiring reliable liquid level control or water quality monitoring. The electrode operates in conjunction with GESTRA level switches (like NRS 1-x series) or conductivity monitoring units (like LRR 1-x series) to provide switching signals based on the presence or absence of liquid at the electrode tip, or to measure the liquid’s conductivity.
