  • The factors that affect the test value of TDS: the temperature of water (the TDS-3 tester cannot test the water with high temperature such as, boiled water). The flow velocity of water (the TDS-3 tester cannot be applied to test the flowing water).
  • If the tester displays a flashing “X10” icon, multiply the reading by 10.
