The unique circuitry of our 750 Series II Resistivity Monitor/controllers guarantee accurate and reliable measurements. 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. A push-to-test button makes setpoint checks easy, while the internal alarm set discourages unauthorized adjustments. Standard on all controller models is a heavy-duty 10 amp output relay, operating on either increasing or decreasing readings. Bright green/red LEDs indicate above/below setpoint readings. | Applications | Deionization (DI) and distillation ultrapure water treatment systems | | Electronics | | Pharmaceuticals | | Laboratories | | Food Processing | | Plating | | Power Plants | | Boiler Condensate | | Process Control |
| All 750 Series II models feature an IP65/NEMA 4X water resistant and corrosion-proof rated enclosure while being a compact size at 6x4.8 inches (15.2x122 mm). They are suitable for panel, bench or surface mounting. Accessories include a 3 Sensor input, a 3 Range switch (both installed separately from the monitor/controller), and a RA™ - Remote Alarm. See pricelist (below) for a complete list of options and accessories. Custom and OEM Models available. Contact us with your requirements. |

Sensors:
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.
