Conductivity calibration
14
● TDS calibration
TDS (Total dissolved solids) is calculated from the measured conductivity value. So no TDS
calibration is required and once conductivity mode is calibrated, TDS values will be recalibrated
accordingly.
Set the required TDS curve in LAQUA EC200 handheld meter. Available TDS curves are;
- LINR (Linear factor with adjustable factor from 0.4 to 1.0)
- 442 (Myron L 442 non-linear curve)
- EN (European environmental standard non-linear curve)
- NACL (non-linear salinity curve)
To set a desired TDS method, refer “P2.1 TDS curve selection” on page 29.
