The 751II is an analog resistivity monitor in the 750 Series II line, designed for continuous process control of ultrapure water in applications such as deionization, pharmaceuticals, and laboratories. It features a 2.5 in./63 mm analog meter display, IP65/NEMA 4X water-resistant and corrosion-proof ABS enclosure measuring 152 x 122 x 96 mm, and operates on selectable 115/230 VAC power. The unit includes a 10-amp SPDT relay with selectable operation on increasing or decreasing readings, green/red LEDs for alarm status, and automatic temperature compensation to 25°C. Built-in electronic calibration and a push-to-test function are standard. It requires a CS10 series sensor for operation and does not include a second alarm or 4-20 mA output.
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.
