The Extech EC210 conductivity / TDS meter is a compact, handheld instrument designed to take quick, accurate measurements of conductivity or total dissolved solids plus temperature in water. It is ideal for applications such as wastewater and drinking water analysis; environmental tests to determine the health of ponds, streams, wells, and other bodies of water; or for manufacturing processes such as component or PCB rinsing.

The EC210 measures conductivity over three ranges (2000 μS/cm; 20 mS/cm; 100 mS/cm); TDS over three ranges (1200 ppm; 12,000 ppm; 66,000 ppm ); as well as temperature from 32 to 122°F. It includes automatic temperature compensation to maintain accuracy. Test results are displayed on a large, dual LCD display. The meter includes Min/Max and Data Hold functions and auto power off (with disable) to save battery life, which make them perfect for field or home use. These portable meters are easy-to-use, precise, and economically priced to meet your budget.
