The Extech EC210 is a compact handheld meter for quick, accurate measurements of conductivity or total dissolved solids (TDS) plus temperature in water. It is ideal for wastewater analysis, drinking water testing, environmental monitoring of ponds and streams, and industrial processes such as component or PCB rinsing.

The meter features three autoranging conductivity ranges: 2000µS/cm, 20mS/cm, and 100mS/cm, and three TDS ranges: 1200ppm, 12,000ppm, and 66,000ppm. Accuracy is ±2% full scale for both parameters. The long-life carbon rod combination electrode is fully replaceable. Temperature measurement from 32 to 122°F (0 to 50°C) with ±1.5°F accuracy is displayed simultaneously.

Automatic temperature compensation (ATC) maintains accuracy, with a compensation factor adjustable from 0 to 5% per °C to suit different solution types. The dual LCD shows conductivity or TDS with temperature simultaneously. Additional features include Min/Max recording, Data Hold, and auto power off with disable function for extended field use. Calibration can be performed using optional 1413µS/cm standard solution. The meter comes with conductivity cell, 1m cable, 9V battery, and soft carrying case. Sampling rate is approximately 1 second. CE certified with 2-year warranty.
