Ammonium With pH And ORP Sensor
PN: 620911
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.
