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.ut.

All models corrected to 25°C. Uncompensated models available to conform with USP 25. The 758II- 111-4A includes a 4-20 mA Isolated Outp

Modifications available for digital models only. To configure the base model, chose a suffix to add to the original model number.

*All 750 II Conductivity models require a CS51 Sensor. These reliable sensors feature an integral temperature sensor to ensure accurate and rapid automatic temperature compensation. The sturdy polypropylene bushing is modular for easy inexpensive replacement. Several alternatives for the metal portion of the sensor are available, depending on the demands of the application.

• CS51LC sensors (0.1 constant) are used <10
• CS51 sensors (1.0 constant) are used between 0-10 and 0-20,000
• CS52 sensors (10.0 constant) are used >20,000
• Low cost, low temperature, low pressure sensors are available upon request
