DO6400/DO7400 Series Dissolved Oxygen Sensor
The DO6400/DO7400 Series Dissolved Oxygen Sensor is a submersible galvanic sensor designed for continuous oxygen monitoring in water. Week Technology Ltd. offers a range of models including DO6400, DO6400TC, DO6441, DO6442, DO7400, DO7400TC, DO7441 and DO7442, each fitted with a large‑capacity electrolyte holder for long‑term deployment. The O2 measuring range covers 0.5‑20 ppm for the DO6400 series, 0‑100 % or 0‑200 % saturation for the TC variants, and 0.03‑20 ppm for the DO7400 series. All models provide either millivolt or 4‑20 mA output signals.
The sensor body is moulded from NORYL, giving chemical resistance and a solid grip when wet. The cathode is silver, while the anode uses zinc in the DO6400 line and lead in the DO7400 line, following standard galvanic cell construction. Users can select PTFE or high‑density polyethylene membranes, both supplied with two spare membranes, an installation tool and electrolyte in the kit. Typical industry practice expects an accuracy of ±0.2 mg L⁻¹ and a response time under 10 seconds for such galvanic sensors.
These sensors are commonly installed in aquaculture ponds, wastewater treatment plants and any process requiring reliable dissolved oxygen data. Week Technology Ltd. ships the units from Shenzhen, China and includes the necessary accessories for quick field installation. Buyers should confirm the required output type, membrane material and any specific packaging requirements directly with the supplier.

Sourcing DO6400/DO7400 Series Dissolved Oxygen Sensor from Week Technology Ltd. - China Import Guide
Before placing an order, confirm the exact model number, desired output type (millivolt or 4‑20 mA) and membrane material (PTFE or HDPE). Request the latest datasheet and, if required, a calibration certificate to verify performance specifications. Verify that the supplier can provide spare membrane kits and the recommended installation tool for field service.
Logistics are handled from Shenzhen, China. Buyers should discuss Incoterms such as FOB Shenzhen and confirm the expected lead time, which is typically four to six weeks after order confirmation. Payment terms are not listed, so negotiate a secure method such as T/T against a verified commercial invoice.
Quality assurance should include a pre‑shipment inspection of the sensor housing, membrane integrity and output calibration. Ask for a functional test report and any relevant conformity documentation. Ensure the packaging contains the sensor, spare membranes, installation tool and electrolyte to minimise handling risk during transport.
