Ohaus Starter ST272 pH Electrode

The Ohaus Starter series of electrodes provide accurate and precise measurements of pH, oxidation-reduction potential, conductivity, dissolved oxygen, and temperature. They are compatible with Ohaus' AquaSearcher and Starter Meters. Their pH electrodes range from basic models to those that support more advanced pH analysis including a glass shaft 3-in-1 electrode, micro sample, double salt-bridge, and flat surface pH electrodes.

The ST272 is a non-refillable, combination pH electrode with an epoxy body, an annular ceramic junction and a BNC connector. The annular junction prevents clogging as it features a special ceramic which encircles the glass bulb.  Numerous pores in the ceramic provide lower resistance and more stable readings.  This electrode features a stainless steel cutting blade making it ideal for the analysis of semi-solid samples such as meat, fruit, cheese and sludge where glass alone may break.
