Conductivity/TDS Digital Monitor/Controller, 0-50 µS, 4-20 mA Module, 115VAC Power Cord
The Myron L 758II-111-4A-PC is a 750II series digital conductivity/TDS monitor/controller with a range of 0 – 50 µS, a 4-20mA self-powered isolated output module and 115VAC power cord (8-ft/2.44 meters with plug and strain relief).
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 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 were corrected to 25°C. The TC may be disabled to conform with USP requirements.
Built-in electronic calibration allows for fast quality checks without standard solutions. (Note: for maximum system accuracy standard solutions are recommended). 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 above or below setpoint readings. All 750 Series II models feature an IP65/ NEMA 4X water-resistant and corrosion-proof rated enclosure. Compact in size at 152 x 122 mm/6 x 4.8 in., they are suitable for panel, bench, or surface mounting.
Conductivity/TDS Sensors
The CS51, CS51LS, and CS51R sensors (sold separately) are suitable for 0-10 through 0-20,000 µS/ppm ranges. These reliable sensors feature an integral temperature sensor to ensure accurate and rapid automatic temperature compensation. The sturdy polypropylene bushing is modular for an easy, inexpensive replacement. Several alternatives for the metal portion of the sensor are available, depending on the demands of the application.
