Cat.No.6400-00
Handy Type Digital pH Meter Model SK-620PH
A handy type pH meter with a PHP-31 electrode.

FEATURES

  • Large LCD for easy reading
    The pH value and the temperature are displayed on a large LCD.
  • Auto Power-Off
    The "auto power-off" function turns off the unit 20 minutes after the power is turned on.
    This conserves battery life if you forget to turn off the unit.
  • Auto temperature compensation
    Once the PHP-31 sensor probe is connected to your SK-620PH, it will perform automatic temperature compensation to produce more accurate pH measurements.
