Brand：Erun
Online Dissolved Oxygen (DO) Water Quality Monitor
Model：ERUN-SZ2-B-A5
Parameter: Dissolved oxygen (DO)
Adopting new generation fluorescent lifetime technology, high performance fluorescent materials are developed by WinRun environmental protection master. No oxygen consumption, no flow rate limitation, no electrolyte required, maintenance and calibration free, excellent stability. Built-in temperature sensor, automatic temperature compensation, RS485 output, can be networked without controller. Widely used in sewage treatment, aquaculture and other industries water quality dissolved oxygen monitoring.
