The difference in values is 40%.
In spite of such large error, some users will continue to take data in
the “NaCl” mode because their previous data gathering and process
monitoring was done with an older NaCl referenced device.
Selecting the correct Solution Type on the Ultrameter II will allow the
user to attain true TDS readings that correspond to evaporated weight.
