LC-EC-4S Keypad Benchtop Conductivity Meter, 0.00 µS/cm-2000 mS/cm (CAT#: STEM-BC-4013-ZJF)

The LC-EC-4S is a high-precision keypad benchtop meter for wide-range conductivity measurement. It is intended for conventional water solutions, education, research, quality control, and advanced laboratory testing. The instrument also calculates resistivity, total dissolved solids, and salinity while measuring temperature. A 6.5-inch white-backlit LCD displays all operating values clearly. The microprocessor supports automatic calibration, automatic or manual temperature compensation, data storage, and configurable settings. Digital filtering and sliding-difference processing improve response and reading accuracy. Eight conductivity calibration solutions are identified automatically from European and US or Chinese standards. A cell with a constant of 10 cm^-1 extends measurement capability to 2000 mS/cm. The system stores 2,000 records and supports USB export, Bluetooth printing, and compatible mobile application access.
