  Resistivity Controllers and Monitors from Myron L Company

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.

Applications

  • Deionization (DI) and distillation ultrapure water treatment systems
  • Electronics
  • Pharmaceuticals
  • Laboratories
  • Food Processing
  • Plating
  • Power Plants
  • Boiler Condensate
  • Process Control

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.

 

All 750 Series II models feature an IP64/NEMA 3 splash 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 for a complete list of options and accessories. Custom and OEM Models available. Contact us with your requirements.

Sensors:

All Resistivity models require a CS10 series sensor. This reliable sensor features 2 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.

Special Order CS41, High Temperature/High Pressure sensor available upon request.
