Summary;
BH-485 series online dissolved oxygen electrode,adopt original battery type oxygen sensing electrode,
and internal electrode to achieve the automatic temperature compensation and digital signal conversion.
With rapid response, low maintenance cost, real-time online measurement. The electrode adopt
the standard Modbus RTU (485) protocol, 24V DC power supply, four wire mode, can be very convenient to
access to sensor networks.
Features
·The on-line oxygen sensing electrode, can work stably for a long time.
