Thank you very much for purchasing the ISFET-pH meters KS701, 723 and the OEM productions IQ120, 125 by Shindengen.

We are a Japanese based engineering company that has been a major producer of ISFET pH sensors and meters. Since 1976, Shindengen had been supplying the ISFET pH meters. The first “truly modular” pocket pH meter design was Shindengen’s KS701, 723 in 1997, and then the OEM productions of minilab IQ120, 125 for IQ scientific. By Shindengen those modular design is a cut above everyone also in tern of quality in the world. But now those models have been discontinued in October of 2008.

In 2007, ISFETCOM made a fresh start as the alternate producer in the ISFET pH meter market by the authority of Shindengen, then we have been supplying the advanced modular models of ISFET pH meter and reference electrode. If, you would like alternative or new one, recommend S2K712,922 and R2K712, we are the people to ask.

For more information please contact Yoshitaka Ito using our contact form.

Please note: “Compatibility” The reference electrode R2K712 is new model which is possible to make one-drop measurement without any contamination and improve the pH-responses of ISFET-pH meters. But it is impossible for the reference electrode IQ RF01-01 to test of one-drop measurement due to the gap between the bottom of reference electrode and FPC film in which will contaminate the sample solution and occur slow response.
