EUTECH Instruments, represented in Australia by Sitest , has released open pore pH electrodes. The solid polymer-gel pH electrode is pressure-resistant and maintenance-free.
The polymer gel provides a stable matrix. This enhances the ability of the electrode to produce reliable results in dirty, ion-weak or protein samples, low pH samples and in the presence of organic solvents. The spear-tip electrode allows direct measurement of samples such as meat, cheese, fruit, yoghurt and other semi-solids without difficulty.
