The Labmart LMCM2P Portable Conductivity Meter is a compact, battery-operated instrument for measuring conductivity, TDS and temperature. It features a backlit LCD, automatic temperature compensation, 1–3 point conductivity calibration, selectable cell constants and memory for up to 100 data sets. The portable design and carrying case make it suitable for laboratory, field and water-quality testing applications. 

Product Overview

The Labmart LMCM2P Portable Conductivity Meter is designed for convenient measurement of electrical conductivity, TDS and temperature across a broad measurement range. The meter automatically ranges across conductivity measurement scales and supports selectable cell constants of K = 0.1, 1 and 10, allowing configuration for different conductivity measurement requirements.

The instrument provides 1 to 3-point conductivity calibration with selectable conductivity standard options and incorporates automatic or manual temperature compensation. Its backlit LCD display provides clear measurement visibility, while the Auto-Read function detects and locks the measurement endpoint.

For data handling, the LMCM2P can store and recall up to 100 data sets and provides a USB interface for data transfer or connection to a power adapter. The supplied carrying case supports convenient transportation for field and on-site testing.
