Brand：Erun
Real-time online water quality ORP analyzer
Model：ERUN-SZ4-A-A2
ORP (platinum electrode method)
ERUN-SZ4-A-A2 real-time on-line water quality ORP analyzer produced by Erun Environmental Protection, its sensor adopts high-performance industrial on-line electrode, which can be used for long time and stable on-line monitoring work, the built-in temperature sensor automatically carries out temperature compensation, and it can be convenient to realize the network and system integration in the case of no controller. It is mainly used in water quality treatment, boiler water, wastewater treatment and chemical, biological and other industries for continuous real-time monitoring of water quality redox potential ORP.
