The Labmart LMCM20H Conductivity / TDS Meter is an auto-ranging microprocessor-based laboratory meter designed for measurement of conductivity, Total Dissolved Solids (TDS), and temperature in liquids. It features automatic conductivity/TDS ranging, up to 3-point calibration, automatic temperature compensation, selectable cell constants, automatic endpoint detection, USB connectivity and memory for up to 100 readings. 

Product Overview

The Labmart LMCM20H Benchtop Conductivity / TDS Meter is designed for laboratory measurement of the electrical conductivity and Total Dissolved Solids of liquid samples, with an additional temperature measurement mode.

The instrument uses automatic ranging for conductivity and TDS measurements and supports conductivity calibration at up to three points. Calibration standards can be selected from 10 µS/cm, 84 µS/cm, 1413 µS/cm, 12.88 mS/cm and 111.8 mS/cm, with any three available for calibration.

Automatic or manual temperature compensation can be selected, while the cell constant can be configured to K = 0.1, 1 or 10. A large white-backlit LCD, automatic read function, 100-reading memory and USB interface support convenient laboratory operation and data handling.
