EziLab offers the Tabletop Conductivity Meter EZL-TCM123, a lab TDS meter that measures conductivity, TDS, salinity, and resistivity from one electrode at the bench. Choose it as a simpler alternative to the 7-inch touchscreen DCM121 when routine water checks need the same core parameters without the larger interface. TDS reads from 0 to 100 g/L, salinity from 0 to 100 ppt, and resistivity up to 100 MΩ·cm for high-purity water, while one-point electrode calibration meets test needs from 0.5 µS/cm to 200 mS/cm. Auto-recognition of 8 conductivity calibration standards speeds daily setup, and automatic temperature compensation corrects readings for sample temperature. A 6.5-inch LCD shows all parameters at once, storage holds 500 test sets for USB transfer, and Bluetooth supports wireless printing. Self-diagnosis flags electrode or setup faults, and IP54 protection resists dust and splashes. A rotary electrode holder keeps the probe positioned between samples, and the 600 g meter runs from a 12 V adapter. Research labs, QC teams, biotech, and fine chemical producers test process and pure water, while water treatment and RO plant labs check common, reverse osmosis, high-purity, and distilled water. Ultrapure water pulls carbon dioxide from room air within seconds, which lowers its resistivity, so plan to read high-purity samples in a covered beaker or flow cell, then compare meters on the Lab Equipment and Laboratory Conductivity Meter pages.
