The pH / redox (ORP) sensor AP100 has a proven track record in a wide range of applications. The AP100’s bayonet technique enables quick removal for maintenance while the double-unlock method ensures safe pressure venting. The sensor is available with general-purpose or low-resistance ‘blue-glass’ for low temperatures. Manufactured in glass-coupled polypropylene, the all-in-one sensor can be supplied for flow-through, dip and submersible applications.
