Extech Spare ExStik II Dissolved Oxygen Electrode Module

Product Code: DO605

The Extech DO605 ExStik® II Replacement Dissolved Oxygen Module is a genuine replacement sensor designed for use with the Extech DO600 ExStik® II Dissolved Oxygen Meter. This galvanic dissolved oxygen module measures both dissolved oxygen and temperature, making it ideal for routine water quality monitoring in aquaculture, fish hatcheries, environmental monitoring, wastewater treatment, and laboratory applications. The module features a replaceable screw-on membrane cap, allowing quick maintenance and minimizing instrument downtime.

The DO605 provides dissolved oxygen measurements from 0 to 20.00 mg/L (ppm) or 0 to 200.0% saturation, with automatic temperature compensation from 0 to 50°C (32 to 122°F). Its waterproof IP57 construction makes it suitable for both laboratory and field use. Regular replacement of the membrane and electrolyte (using the Extech DO603 Membrane Kit) helps maintain fast response times and measurement accuracy.
