Myron L 753II Digital Resistivity Monitor and Controller
The unique circuitry of the 750 Series II Conductivity Monitor/controllers guarantees accurate and reliable measurements. Drift-free performance is assured by "field-proven" electronics, including automatic DC offer compensation and highly accurate drive voltage.
Since temperature compensation is at the heart of accurate water measurement, all Myron L monitors/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 temperature compensation may be disabled to conform with USP requirements.
Built-in electronic calibration allows for fast quality checks without standard solutions. For maximum system accuracy, standard solutions are recommended.
A push-to-test button makes set point 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 reading. Bright green/red LEDs indicate above or below-set point readings.
All 750 Series II models feature an IP65/NEMA 4X water-resistant and corrosion-proof rated enclosure. Compact in size at 6" x 4.8", they are suitable for panel, bench, or surface mounting.
