750 Series II Resistivity Monitor/Controllers
The unique circuitry of our 750 Series II Resistivity Monitor/controllers guarantees 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 are corrected to 25°C. The TC may be disabled to conform with USP requirements.
Built-in electronic calibration allows for fast quality checks.
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 readings above or below setpoint.
Digital and Analog 750 Series II models have an IP65/NEMA 4X water-resistant & corrosion-proof rated enclosure. At 152 x 122 mm/6 x 4.8 in., all models are suitable for panel, bench or surface mounting.
Additional options include a 3 Sensor Input Switch and/or a 3 Range Switch and a Remote Alarm™ model RA.

Resistivity Sensors
All 750 Series 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.
Limited Warranty
All Myron L® Monitor/controllers have a Two (2) Year Limited Warranty. pH Sensors have a Six (6) Month Limited Warranty. If any Monitor/controller fails to function normally, return the unit to the factory prepaid. If, in the opinion of the factory, failure was due to materials or workmanship, repair or replacement will be made without charge.
A reasonable service charge will be made for diagnosis or repairs due to normal wear, abuse or tampering. Warranty is limited to the repair or replacement of Monitor/controller only. The Myron L® Company assumes no other responsibility or liability.
