Introduction
1.3 RESISTIVITY CELLS
All 750/760 Series Monitors use a CS10 Cell. These reliable
sensors feature two integral thermistors to ensure accurate and
rapid automatic temperature compensation. The sturdy
polypropylene bushing is modular for easy, inexpensive
replacement. Several alternatives for the metal portion of the cell
are available, depending on the demands of the application.
