TopLine electrodes combine reliable measuring results with a maximum dwell time. They were developed for a wide range of applications in the lab, field and processing of wastewater via emulsions, solutions with proteins, suspensions all the way to purely aqueous samples.

• Peek shaft for the highest mechanical and chemical resistance
• Most precise measurements thanks to proven process membrane glasses and reference system
• Maximum dwell time by means of a reference electrode with microdispersed KCI solid electrodes (DuraLid) as well as a multi-diaphragm system with external fibre wick hole and internal labyrinth reference element (LoopRef)
• Available as analogue electrodes or as digital electrodes with IDS® and Memosens® head
