ISFET pH meter S2K712 & S2K922

                   ISFETCOM- S2K712 unbreakable ISFET pH Meter

                   This advanced Pocket ISFET pH Meter gives fast, accurate pH readings

                   with samples as small as 50uL.

                   The non-glass, ISFET pH sensors eliminates problems associated with

                   delicate glass pH Meters (see:


                   One-point calibration and pH & temperature readings in seconds make this an

                   ideal choice for a wide range of applications.


                   The R2K712 silicon electrode sensor is compatible with IQ Scientifics'

                   Mini-Lab Pocket pH meters IQ120,  IQ125 & IQ128. ( see:
