Palintest Pocket TDS Sensors are simple to use pocket sized instruments for checking the total dissolved solids content of water and aqueous solutions. The TDS sensor calibration is based on the established factor that TDS equals conductivity x0.67 at 25°C (except TDS Salt Pool Sensor which uses a factor of 0.55).
Recalibration
For optimum performance, recalibrate the sensor regularly. Weekly recalibration is recommended if the sensor is in constant use. For calibration use Palintest Standard TDS/Conductivity Solution.
What is conductivity? Conductivity is a measure of the ability of a substance to conduct an electrical flow through it. In water, many compounds and molecules (such as dissolved salts and inorganic materials) dissociate into constitutive ions. Ions are small sub-atomic particles and carry with them an electrical charge; either positive (cations) or negative (anions). These particles help condu...
