Primatrode with NTC (IP67, fixed cable 1.2 m)

Primatrode with NTC (IP67, fixed cable 1.2 m)
Order number: 6.0228.020

Combined pH electrode with integrated temperature sensor (NTC) and fixed cable conforming to IP67 (1.2 m).
This electrode is suitable for an introduction to GLP-compliant pH measurements in solutions that do not contain precipitates, proteins, or sulfides. This electrode is mechanically resistant thanks to the robust/unbreakable plastic shaft made of polypropylene and impact protection for the glass membrane.
Additionally, this electrode offers a waterproof plug for mobile use with Metrohm pH meters.
Reference electrolyte: c(KCl) = 3 mol/L, storage in storage solution.
