FEATURES

* Lipuid supply system and tools used for semiconductor processing (Scrubber, D.I Water Line, etc.)

* Extremely low internal volume

* Fig. 3-1 is a block diagram for measuring the ISE pH-sensor

* Electrode composed of a reference electrode and an internal electrode was used as the composite electrode ISE used in the experiment. Electrodes filled with Sat.KCL (3 mol) were sued in this experiment and electrodes were electroplated with Ag / AgCL 

* Also, we used Orion's Buffer Solution pH 7 and pH 10 to measure linearity and response speed. And we measured reliability by dipping ISE in a HF solution composed of HF(Hydrofluoric Acid, J.T Baker) mixed with deionized water in 100:2 ratio
