Cond/TDS Digital Monitor Only, 0-50 ppm, NaCl ppm, 4-20 mA Isolated
The unique circuitry of the 750 Series II Resistivity Monitors 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 Monitors 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 to 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.
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.
Additional options include a 3 Sensor Input Switch and/or a 3 Range Switch and a Remote Alarm model RA.
Note, this version 759II-112N-4A is the monitor only with no relay, LED indicators or set point switch. This version includes the optional 4-20mA output for PLC or SCADA operations and NaCl ppm.
