Calibration with Conductivity Standard and TDS factor
For CON 410 meter only
The concentration of salts dissolved in solution increases the conductivity of that solution. This
relationship varies from salt to salt and is roughly linear over a given range for a given salt.
The TDS conversion factor is the number used by the meter to convert from conductivity to
TDS.
Instead of calibrating for TDS directly (described in Section 4.5.1), you can calibrate the CON
410 meter by:
1.
calibrating to conductivity standards (as described on pages 10 to 11) and then
2.
entering the appropriate TDS conversion factor into the meter.
To determine the conductivity to TDS conversion factor for your solution:
• Addendum 2 explains the formula to calculate the conductivity-to-TDS
conversion factor.
Enter the TDS conversion factor into your meter as described under Section 7.5.4, in P4.4
Setting the TDS Factor on page 33.
