Myron L 757II Analog Conductivity/TDS 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 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 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 LED's 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.
