We offer the portable electrical conductivity meter 'CM-21P/31P', which makes it easy to measure electrical conductivity in the field. Electrical conductivity indicates how easily electricity can pass through water; the more electrolytes present in the water, the more current flows. Since the amount of electrolytes is almost proportional to the dissolved solids in natural water and water supply, electrical conductivity can also be used as an indicator of dissolved solids. 【Measurement Range】 ■ Electrical Conductivity: 0.1mS/m to 10S/m (CM-21P), 0.1mS/m to 10S/m (resolution: 4 significant digits) (CM-31P) ■ Electrical Resistivity: 0.1Ω·m to 10kΩ·m (CM-21P), 0.1Ω·m to 10kΩ·m (resolution: 4 significant digits) (CM-31P) ■ Salinity Conversion: 0 to 4.00% (CM-21P), 0.00 to 4.00% (resolution: 0.01%) (CM-31P) ■ Temperature: 0 to 80℃ (CM-21P), 0.0 to 100.0℃ (resolution: 0.1℃) (CM-31P) *For more details, please download the PDF or feel free to contact us.
