Drumline Ltd is a UK manufacturer of a comprehensive range of highly competitive water column conductivity probes / electrodes. All our probes are manufactured 100% in UK and supplied with a certificate of origin. Our range includes guaranteed direct replacement probes for companies such as Clark Reliance, Solartron, Levelstate Systems, Emerson, Mobrey, Hydrastep, Cesare Bonetti, Narvik Yarway, Yarway, Fossil, Quest-Tec, Penberthy & Tyco.

Our specialist techniques and high quality materials mean that all our conductivity probes are probably the best on the market. Not only that, they are very competitively priced.

All probes are vacuum brazed, Helium leak tested and Hydo tested to ensure that they meet our exacting standards. We use a high tolerance Zirconium insulating ceramic to ensure extra long life. The brazed metal to ceramic joint is further protected by an ultra tough gilding process. We use high quality stainless steel for all the metal parts of the probes, this gives the best combination of thermal expansion properties, brazing properties, toughness and finish.

Drumline has used decades of experience in the conductivity probe industry to further refine the designs of its direct replacement conductivity probes.


The DLRZG020RK is a direct replacement for the Levelstate Type 871 probe.
