I have "84uS/cm" "12.88mS/cm" standard conductivity buffer solution.
Code is designed only for 1413 uS/cm standard buffer solution.
following formula is only for 1413 uS/cm standard buffer solution.
tdsValue=(133.42*compensationVolatge*compensationVolatge*compensationVolatge - 255.86*compensationVolatge*compensationVolatge + 857.39*compensationVolatge)*0.5; //convert voltage value to tds value

How can i calibrate TDS sensor for 84uS/cm & 12.88mS/cm??
What is the formula for 84uS/cm & 12.88mS/cm??
Thanks!!
