Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of do electrode in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk do electrode in stock here from our factory. We also accept customized orders.
The Qiwei dissolved oxygen( DO) electrode was created to measure dissolved oxygen in laboratory analyses, compatible industrial monitoring systems, and water quality testing. It is applicable to a variety of industries, including aquaculture, environmental monitoring, and some business water processes.
Finding the ideal Would electrode requires more than just checking the assessment range, for manufacturers of laboratory equipment, distributors of water quality instruments, and industrial system integrators. The suitability of the last construction depends on measurement technologies, response time, temperature compensation, sensor maintenance, and sensor compatibility with the attached meter or controller.
Qiwei accepts custom orders and provides Would electrodes for a variety of assessment needs. Give your application, the device model, and operating conditions to help you find the best configuration, whether you're looking to purchase new electrodes for lab equipment or go over sensors for an industrial monitoring project.
product key technologies
The dissolved oxygen (DO) electrode is a key sensor used to measure the concentration of dissolved oxygen in water. It is widely applied in wastewater treatment, aquaculture, environmental monitoring, laboratory research, and various industrial water process systems.
Adopting either polarographic or optical fluorescence measurement technology, the DO electrode features fast response, high stability, strong anti-interference ability, and low maintenance requirements. It is waterproof, corrosion-resistant, and supports multiple installation methods including immersion, flow-through, and pipeline mounting.
When used with a transmitter or multi-parameter water quality analyzer, it enables real-time and accurate monitoring of dissolved oxygen, helping users control water quality and optimize process operation efficiently.

How to Select a DO Electrode for Laboratory or Industrial Use?
The ideal dissolved oxygen electrode is based on the assessment atmosphere, desired response, instrument compatibility, and maintenance requirements.
Assessment at a laboratory Would
Selection should be made for laboratories, research institutes, universities, and quality control departments based on dimension range, response time, temperature, instrument compatibility, and consistent operating procedures.
Verify the following before placing an order:
- Conformity with the laboratory Would meter
- Needed temperature and range for measuring dissolved oxygen.
- The check procedure's response time requirements.
- Testing and validation procedures.
- Repair instructions and replacement parts availability.
A reliable laboratory DO electrode can be used to carry out regular research, quality control, and water quality testing.
DO monitoring on-site and in the business sector
Selection should take into account installation conditions, ongoing or regular operation, cleaning entry, cable routing, and maintenance intervals for wastewater treatment facilities, aquaculture systems, and commercial water processes.
Verify: Before installing:
- Integration with the business DO controller or transmitter.
- Conformity to the operating temperature and operation waters.
- The preferred flow-through, network, or absorption method.
- Access to alternative components and requirements for sensor maintenance.
- the necessary checking frequency and measurement response.
The entire measurement system must be evaluated for business applications. Compatibility with all online transmitters and controllers cannot be guaranteed by a good electrode only.
FAQ
1. What is the measurement range of the Qiwei DO electrode?
The temperatures range for dimension is 0 to 40 degrees Celsius, while the published dissolved oxygen range is 0 to 20 mg/L. The published fundamental error is 0. 3 mg/L for temperature and 0. 3 mg/L for dissolved oxygen. Before placing an order, check the relevant specifications for the product configuration you want.
2. What is the response time of the DO electrode?
At 20°C, the published response time is only 30 seconds, or 90%. The actual answer may depend on the ambient heat, sample conditions, sensor conditions, and measurement setup.
3. What is the difference between polarographic and optical fluorescence DO sensors?
Optic fluorescence sensors measure a luminous sensing material's oxygen-dependent response while polarographic sensors measure it through an electrochemical process. Their repair procedures and replacement parts may vary. Choose a detector that is compatible with the device and its requirements.
4. Does the DO electrode support automatic temperature compensation?
The recommended programmed temperature range is 0 to 40 degrees Celsius. Make sure the linked meter or controller adheres to the established measurement protocol and has the necessary temperature compensation function.
5. How often should the membrane and electrolyte be replaced?
The sensor's architecture, operating conditions, sample contamination, and manufacturer's recommendations for a replacement frequency vary. Follow the model-specific maintenance instructions and make sure the anode you choose uses a replaceable membrane and electrolytes.
6. Can the DO electrode be connected to an industrial online DO meter?
Compatibility is determined by the electrode technology, electric software, measurement range, and controller requirements. To find out if a particular electrode and receiver model can be used together, call Qiwei.
7. Can laboratory equipment distributors purchase DO electrodes in bulk?
Indeed, inquiries about purchasing in bulk and in bulk are welcome. To get a construction review and quote, please provide the necessary quantity, intended application, suitable instrument model, and any replacement-part requirements.
8. Can I request replacement parts or a sample before bulk purchasing?
Call Qiwei to verify availability of samples and available replacement parts for the selected model. To allow the team to examine your request, include the item model, application, and necessary components.
