Total Dissolved Solids (TDS)

Method

In industrial water systems, it is important to accurately measure and control the amount of dissolved solids present, as they can form deposits on the system components and decrease overall system efficiency.  The National Secondary Drinking Water Standard for TDS is 500 mg/L.

 

Method of Operation.

To operate the CHEMetrics Total Dissolved Solids (TDS) Meter (Cat. No. I-1100), switch unit on, remove the electrode cap, immerse the probe into the sample, making sure that the sensor is fully covered.  Wait for the readings to stabilize (Automatic Temperature compensation corrects for temperature changes).  Take measurement.  To clean the probe, simply mix it in tap water.  Tester is factory calibrated.  However, to ensure accuracy, calibrate the TDS meter on a regular basis.
