■ Sensor deterioration diagnostic during measurement *2
■ Optical DO sensor connectable (optional)
■ Sample adjustment function
■ Automatic potassium ion concentration compensation
Deterioration diagnostic function during continuous measurement. This function reduces the risk of sudden loss of measurement and provides more reliable measurement.
■ Replaceable chip without the need for tools
■ Combination with new-type ultrasonic cleaner improves antifouling property (optional)
■ Flat sensor surface (prevents bubble and stain accumulation) *2
■ No measurement reagent necessary
Enables continuous cleaning without damaging sensor, and long term adhesion prevention of stain.
■ The ion sensor enables long term stable measurement
■ New ion chip internal solution enables stable measurement (Japan patent No. 5144829)
■ New structure of reference chip achieves stability measurement *1
