Reverse Osmosis: RO Meters from Myron L Company
With a single before and after test, this handy device effectively demonstrates how your RO or distillation system eliminates harmful dissolved solids. It will also service test systems, including membrane evaluation programs.
Automatic Temperature Compensation:
Why It Is Important
The graph below illustrates a TDS reading of a 500 ppm water sample tested with a non-temperature compensated conductivity meter. The same water sample appears to have a higher level of TDS when heated (and lower TDS when chilled). Actually, only conductivity readings change with temperature. TDS does not change.
Many instruments ignore the importance of temperature. Others require a separate thermometer for testing sample temperature, then manual adjustment of the meter. All Myron L instruments, however, feature fast and precise Automatic Temperature Compensation. The result: a more accurate, useful instrument.
How Conductivity Measures ppm/TDS
Total Dissolved Solids (TDS) conduct electricity. This conductivity allows measurement of the concentration of these salts directly in parts per million (ppm). However, the salts composition in waters can vary significantly by location. Since various salts pass current differently, it was necessary to determine an average ppm/ conductivity relationship. The Myron L Company established the 442 Standard over 40 years ago. It remains the worlds most widely accepted standard of its kind.
If You Also Test pH
Myron L offers instruments that check both TDS and pH, and are widely used throughout the RO industry.
