Drift free performance is assured by "field proven" electronics, including automatic DC offset compensation and highly accurate drive voltage. Since temperature compensation is at the "heart" of accurate water measurement, all Myron L Monitor/controllers feature a highly refined and precise TC circuit. This feature perfectly matches the water temperature coefficient as it changes. All models corrected to 25°C. Uncompensated models available to conform with USP 25.

The 753II- 11-SC-4A-PA-PC includes a second Control Module, 4-20 mA Isolated Output, a Piezo Electric Alarm, and a power cord. See additional options for modification below.

Modifications available for digital models only. To configure the base model, chose a suffix to add to the original model number.

*All 750 II Resistivity models require a CS10 series sensor. This reliable sensor features two integral thermistors to ensure accurate and rapid automatic temperature compensation. The sturdy polypropylene standard bushing is modular for easy, inexpensive replacement. A PVDF or 316 stainless steel bushing can also be ordered. The metal portion is available in either 316 stainless steel (standard) or titanium.
