Range 0~14 for PH,-1000~1000mv for ORP Two switching contacts as set-point relays Automatic or manual temperature compensation
WELLORE WL series PH/ORP monitor & Electrode
pH/ORP(WL900) is a kind of precise instruments used for test and control pH/ORP. It could store, calculate and compensate all the parameters related to testing pH/ORP value, such as the temperature characteristic of pH electrode, the slope deviation of pH/ORP electrode, etc. It has the merits of complete functions, stable performance and simple operation, which makes it as the choice for the enterprises to test and control pH/ORP.
pH/ORP serial instruments could be equipped with various kinds of pH electrodes (especially those with HF media and stibium mode).
