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.

    Reliable measuring results over long periods of time can be guaranteed only if the pH glass membrane and the diaphragm receive preventive and regular care. Cleaning by etching with toxic chemicals or applying mechanical treatment to the diaphragm is not only complicated and expensive, it also accelerates the ageing of the pH glass electrode.
    The cleaning solution was developed for easy and gentle cleaning of pH glass electrodes. Regular use can considerably prolong their service life.

    This cleaning solution is also part of the pHit kit.
