The ES-421 hand held salt meter is a great tool for getting quick results and taking action fast.  We just finished a Podcast with Atago discussing the issues surrounding salt testing.  Learn More about the ES-421 Digital Salt Meter.

• Why do we test for salt? 

• How do we test salt (sodium chloride)? 

• What options do we have in testing for salt? 

• How should someone approach salt testing procedures?

You can improve your results by diluting your sample! For those samples with more salt content simply make a mixture with 10% sample and 90%water (for example) = 100%. Mix your solution and then take your reading. Since the sample only accounts for 10% of the solution the operator can then take a reading and calculate the result as a % or decimal point of the reading.
