Resistivity Monitor/Controllers 751-752-753-754 models

Resistivity Monitor/Controllers 751-752-753-754 models

BENEFITS

  • Affordable
  • Ease of Operation
  • Low Maintenance
  • Ensures Product Quality

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 25C. 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.
See 750II Sensor Selection Guide.

Note: Special Order, CS40 and CS41, High Temperature/High Pressure sensors available upon request.
