About DIGITAL CONDUCTIVITY TDS/METER 641

FEATURES

Extremely Useful for Water Analysis

Highly Stable and Accurate

High Sensitivity Range

3 Digit Display

Digital Conductivity/TDS Meter 641 is extremely useful for fast and accurate determination of Total Dissolve Solids in liquid. A high content of dissolved solids elevates the density of water influences osmo-regulation of fresh water organisms and reduces solubility of gases thereby reducing the utility of water for drinking, irrigation and industrial purpose. Therefore, determination of Total Dissolved Solids in one of the important parameter in water analysis

The use of solid stat technology and IC circuitry makes the instrument versatile and reliable. The instrument is ideal for testing water, drinking water, waste water brine solution, sea water and soluble salts etc.
