Broadsensor online ISE (NH4+ pH ORP/K+) sensor with integrated digital electronics for plug and play capability with Broadsensor multi-parameter sonde platform and IP68 connector to any PLC or RTU. It has a unique design that incorporates a user-replaceable electrode tip (module) and a reusable sensor base that houses the processing electronics. This allows users to reduce the costs and easy to maintain.
Key Advantage：
• Polymer membrane ISE ammonium and potassium electrode.
• a potassium chloride (KCl) solution reference.
• Isolator and NTC10K inside, easy to use.
• User-replaceable ammonium, potassium, pH, ORP, reference electrode,reusable sensor base.
• RS485 output, Modbus protocol.
• IP68 connector.
• All parts designed and made by Broadsensor including ISE.
Note: Freshwater application only.
