Instrument characteristics

1.7-inch color high-resolution (1024 * 600) capacitive touch screen, UI design, navigation style operating experience, high sensitivity, complete parameter display, intuitive, easy to use and simple. The host shell is made of PEEK material, which is resistant to high temperature, corrosion and aging.

2. Built in ARM32-bit microprocessor chip, using digital filtering and slip technology to intelligently improve the response speed and measurement data accuracy of the instrument. The circuit board adopts SMT surface mount technology, which improves the reliability of product processing.

3. The main interface of the instrument can display conductivity/dissolved oxygen concentration/dissolved oxygen saturation/temperature values simultaneously. Clicking on each item module allows you to view detailed detection values for each item and perform calibration for each item.

4. Compliant with international GLP requirements, it has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, USB output, clock display, wireless printing, function settings, and self diagnostic information.

5. The instrument is equipped with a bilingual operating system in both Chinese and English, with user-friendly operation design. The brightness of the instrument can be adjusted, and the temperature unit can be freely switched between ℃ and ℉. The instrument is equipped with temperature electrodes that can automatically perform temperature compensation.

6. The built-in large capacity storage can store 500 sets of measurement data, which can be transferred through USB storage. The stored data can be opened with the general office software EXELL, which greatly facilitates customer editing.

7. The instrument can be equipped with a Bluetooth module, which supports wireless Bluetooth printing and is convenient for users to operate.

8. An intelligent IoT platform system based on WeChat mini programs, which allows real-time viewing of instrument data by downloading programs on mobile phones.

9. The new structure of the polarographic dissolved oxygen electrode can simultaneously measure temperature and dissolved oxygen, and electrode polarization only takes 3-5 minutes. When using a combination diaphragm cap to replace the sensitive membrane, simply tighten the new diaphragm cap onto the electrode, which is extremely convenient to use.

10. The dissolved oxygen measurement mode has the functions of automatic temperature compensation, salinity compensation, and pressure compensation.

11. Scalability: Replace different electrodes (choose electrodes with different electrode constants) to measure conductivity.

12. Automatically identify 8 types of conductivity standard solutions, with two series of standard solutions to choose from: European and American series and Chinese series.

13. ※ 13. It can intelligently determine the electrode status to ensure accurate use by customers.

14. Switchable conductivity TDS、 Salinity and electrical resistivity. TDS and salinity are calculated using polynomials to ensure full range conversion accuracy.

Designed to meet the IP54 dustproof and splash proof rating.
