Description

• With solid membrane Interchangeable flat surface
• Ion to be detected passes through the membrane generating a difference of potential, proportional to ionic concentration
• Analysis time is generally less than one minute
• Sample preparation steps such as filtering or Distillation rarely necessary
• Calibration should be carried out as often as possible (once a day) at the same temperature as the sample
• Measurement temperature 0 to 50°C
• Delivered with membrane, electrolytic solution, ISAB solution and ISE standard and gasket

ISAB solution

: To adjust the ionic strength. add directly to the solution to be measured.

ISE standard

: For the calibration of ionic electrodes. Concentration 1000 ppm.

Specifications

• Filling Solution Type: ISAB/ISE
• Electrode: Combined ion-selective
