Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of conductivity sensor element in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk conductivity sensor element in stock here from our factory. We also accept customized orders.
In laboratory tests, water care, and other industrial process applications, qiwei conductivity sensor elements were created to measure the electrical conductivity of aqueous solutions. DJS-0, DJS-1, and DJS-10, which have minimum cell constants of 0, 1, 1, and 10, respectively, are available standard models.
More than just matching the cell regular, for manufacturers of laboratory equipment, water treatment system integrators, and distributors of industrial instruments, is choosing the correct conductivity sensor. Even taken into account are the sample conductivity, operating temperature, pressure, installation technique, and cable connection.
product key technologies
The conductivity electrode is a key sensor used to measure the conductivity, total dissolved solids (TDS) and salinity of aqueous solutions. It is widely applied in water treatment plants, environmental monitoring, aquaculture, boiler feed water, pharmaceutical production, food and beverage processing, as well as various industrial process water systems.
Featuring high sensitivity, fast response and excellent corrosion resistance, the conductivity electrode ensures stable and accurate measurement in long-term online operation. It supports a variety of installation methods, including immersion, flow-through and pipeline installation, and is compatible with most conductivity meters, controllers and multi-parameter water quality analyzers.
With a robust structure and low maintenance requirements, it provides reliable data support for water quality monitoring, process control and water purification management.
Precaution
1. The conductive electrodes come in two types: shiny and platinum-coated black. The purpose of the platinum-coated black is to increase the effective area of the electrode sheet and prevent and reduce electrode polarization when measuring the conductivity of solutions with high conductivity. Therefore, using platinum-coated black electrodes is more suitable.
2. Before using the platinum black electrode, it can be immersed in distilled water to prevent the black platinum from oxidizing. If the platinum black electrode malfunctions, it can be immersed in deionized water for 2 minutes, then cleaned with distilled water and measured.
3. If the platinum black coating peels off or fades, the platinum black needs to be re-electrified to ensure the accuracy of the measured data.
4. The electrode constant of the conductance cell marked on the electrode at the time of manufacture is only for reference. To verify the accuracy of the marked conductance cell constant, one can refer to the temperature and concentration of the standard solution being measured, look up the corresponding conductance C of the standard solution, and then calculate the conductance cell constant K based on the actual measured display value P of the conductance meter: K = C/P.
Usage
The conductive electrode is made of pure platinum sheet or pure platinum ring and serves as the measuring element of the conductivity meter. It is used to measure the conductivity of liquids or as an indicator electrode for conductometric titration.

- Electrode configuration: Please specify the cell regular and sensing element configuration.
- Bulk supply and project coordination: Provide the expected order quantity, delivery schedule and target application for quotation planning.
Before an order can be placed, professional review should be conducted to confirm custom specifications. Availableness depends on sensor style, manufacturing feasibility, and minimal order requirements.
For a faster evaluation, please share your existing sensor drawing, connector reference, cable length, required cell constant and expected annual purchasing volume.
FAQ
1. What is a conductivity sensor element used for?
A liquid's electric conductivity is measured by a permeability sensor element. It is used in programs like measuring business processes, water quality testing, and monitoring purified water. The correct detector will depend on the sample's characteristics and the expected conductivity range.
2. How do I choose the correct conductivity cell constant?
Select the expected conductivity range for the cell continuous. For more conductive solutions, higher cell constants are usually used, while lower cell constants are usually used for water with lower conductivity. Always confirm the sensor's true dimension range and its compatibility with the attached meter.
3. Does Qiwei offer a K = 0.01 conductivity sensor?
DJS-0, DJS-1, and DJS-10 are the current list of standard designs. Contact Qiwei to verify availability and compatibility before placing an order if your application calls for a K= 0.01 sensor for water that is very low-conductivity.
4. What materials are available for conductivity sensors?
The detector design and model are dependent on the material choices. While system, housing, and sealing materials can be used in conductivity cells, or both platinum- and platinum-black sensing elements can be used. Verify the actual material requirements and chemical compatibility with the software you want to use.
5. Can the conductivity sensor be installed in a pipeline?
The sensor's electrical design and compatible mounting accessories are necessary for pipeline installation. Before purchasing, check the assembly orientation, insertion length, sealing technique, and connection thread before purchasing.
6. Can I request a custom cable length or connection?
Personalized purchases are accepted by Qiwei. Offer the professional team with the necessary cable length, connector type, mounting interface, and drawings so they can determine the suitability and confirm the current configuration.
7. Can I request a sample before placing a bulk order?
To discuss the availability of samples for specialized evaluation, please get in touch with Qiwei. Please include the model, software, and estimated quantity so that the team can verify the cost, shipping, and sample arrangements.
