Page 4: Introduction
Pharmacopœia (USP 23) requirements for continuous monitoring and control of the conductivity of demineralised water, and de-ionised water. The 4623 model is a wall-mounted instrument and the 4628 4623/500 model a panel-mounted, DIN sized instrument. Both instruments have a single programmable conductivity input (Wall-Mounted Model) channel and a single temperature input channel. -
