Offering on/off and continuous process control, the Type 8205 pH controller combines a flat glass sensor and PID-controller/display within a single, splash-proof, plastic NEMA 4 enclosure. It can be integrated with the sensor or remote via a panel or wall mount. As an added feature, the pH controller indicates when the probe is 50% and fully expired when calibrating. The fittings are available in stainless steel, brass, PVDF, PP and PVC, with process connections that include threaded, TriClamp, true union and sanitary.
