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.
