750 Series II Resistivity Monitor Myron L

 750 Series II Resistivity Monitor Myron L

The Myron L 750 Series II Resistivity Monitor is a high-precision monitoring and control system designed specifically for ultrapure water and high-resistivity applications. Its advanced circuitry ensures drift-free, highly accurate measurements with robust temperature compensation. Housed in a compact, IP65/NEMA 4X rated enclosure, this monitor is ideal for installation in demanding environments. With built-in calibration, isolated recorder output, and reliable sensor compatibility, it provides exceptional performance for laboratory, industrial, and pharmaceutical settings.

Features

1. Accurate, Drift-Free Measurements

   • Features automatic DC offset compensation and precision drive voltage for reliable and stable resistivity readings over long-term use.

2. Advanced Temperature Compensation

   • Automatic temperature correction to 25°C ensures precise resistivity measurements. Temperature compensation can be disabled to meet USP standards.

3. Rugged, Water-Resistant Enclosure

   • Compact IP65/NEMA 4X-rated housing provides excellent protection against water, dust, and corrosion, suitable for panel, surface, or bench mounting.

4. Flexible Output and Alarm Functions

   • Includes a heavy-duty 10 amp relay that operates based on increasing or decreasing readings. Bright green/red LEDs indicate above/below setpoint status.

5. Built-In Calibration & Test Features

   • Electronic calibration for fast checks without solutions, and a push-to-test button for convenient setpoint verification. Internal alarm settings prevent unauthorized changes.

6. Recorder and Control Integration

   • Isolated 0–10 VDC output for recorder integration; options for 3-sensor and 3-range switching, with additional remote alarm capability (RA model).
