I am happy to present you precission PH metering solution with input impedance more than 10^13 OHM and 50(uVRMS) noise floor. This was first time, when ILEM-DESIGN was involved in so compilcated project in terms of circuit design and PCB routing. Almost anything matters there... and WE DONE IT!!!

During implementation of this project ILEM-DESIGN was involved in following tasks:

* Precission analog circuit design

* PCB design

* Prototype assembly
