JC-CACO-243/ JC-CACO-243H Online Concentration Meter

When JC-CACO-243 is working, the high-frequency vibration generated by the built-in motor produces different vibration frequencies in the liquid medium with different densities and concentrations, and the vibration frequencies are detected by a piezoelectric crystal, and then converted into a digital signal of density and concentration by a microprocessor through a phase-shifting and amplifying circuit; usually, for liquids with different densities, the densities and concentrations will show a certain mathematical relationship. Usually the density and concentration of different concentrations of liquid will show a certain mathematical relationship, and calculate the corresponding concentration value under a certain density.

7.Using 4.3-inch touch screen man-machine interaction interface, simple atmosphere, more detailed display, convenient operation, strong expandability, can be customized according to user needs interface and functionality;

8.Automatic data storage, easy to query: historical data query, generate historical data curve, quick query, export EXCEL, automatic data analysis and summary, data retention period of 12 months, easy traceability (optional JC-LST historical data storage function is required);

9.Support sqlite database, can store up to 16G of historical data, data can be exported to the computer via USB flash drive or transmitted to PLC, PC, DCS and other upper computer systems in real time via wireless remote transmission function; through the PC remote view of the real-time status, historical records and alarms. (Optional JC-LOT data acquisition system is required);

10.Continuous measurement, rapid feedback, eliminating manual testing errors, no longer need to manually sample and test frequently, saving a lot of manpower and financial resources to ensure data consistency and improve product quality;

11.The use of intelligent chip, running without reagents and consumables, low power consumption, high stability, long service life.
