Specific Conductance

Conductance by Conductivity Meter (EPA 120.1)


This method determines conductance of drinking, surface, and saline water, domestic and industrial wastes and acid rain (atmospheric deposition).

The specific conductance of a sample is measured by use of a self-contained conductivity meter, Wheatstone bridge-type, or equivalent. Samples are preferable analyzed at 25oC. If not, temperature corrections are made and results reported at 25oC.

Method Data

Method 120.1
Hold Time24 hours, unpreserved, 28 days preserved
PreservationAnalyses can be performed either in the field or laboratory. If analysis is not completed within 24 hours of sample collection, sample should be filtered through a 0.45 micron filter and stored at 4oC. Filter and apparatus must be washed with high quality distilled water and pre-rinsed with sample before use.
Sample Volume250mL HDPE bottle
InstrumentationConductivity Meter
