1.0 mS/cm x 700 makes 700 ppm The 640 scale uses a conversion factor of 640 to convert from mS/cm to ppm: 1.0 mS/cm x 640 makes 640 ppm For our experiment, we will first measure the total dissolved solids in distilled water. The meter shows 0 ppm and the multimeter shows 1.21 M...
To obtain the conductivity from the measured conductance, the following formula is used: σ = K ∙ G where σ is the solution conductivity in S/cm, K is the cell constant in cm⁻¹, G is the cell conductance in siemens. The cell constant is usually not calculated, but measured for...
