Myron L (758II-121-4A) 0-2000 uS with Optional 4-20 mA Isolated Output Digital Display
Myron L 758II-121-4A Performance Specs
750 Series II Controller Features
| Model Number | Myron L 758II-121-4A |
| Monitor Technology | Drift-free circuitry with automatic DC offset compensation |
| Control Mode | Increasing or decreasing setpoint operation with internal alarm lock |
| Display & Indicators | Digital readout with green/red LED status indicators for above/below setpoint |
| Mounting Options | Panel, bench, or surface mount configurations |
| Setpoint Testing | Push-to-test button with internal alarm lock to prevent unauthorized adjustments |
| Available Accessories | 3 Sensor input, 3 Range switch, RA Remote Alarm (installed separately) |
Industrial Water Quality Control
The Myron L 758II-121-4A conductivity monitor is designed for continuous water quality monitoring in industrial, commercial, and laboratory applications where precise conductivity measurement and automated control are required. The 4-20 mA isolated output allows seamless integration with PLCs, SCADA systems, and building management systems for remote monitoring and data logging. Ideal for reverse osmosis system monitoring, boiler feedwater control, cooling tower management, and process water applications where maintaining specific conductivity ranges is critical. The automatic temperature compensation circuit adjusts readings accurately across varying water temperatures, while the heavy-duty relay can directly control pumps, valves, or chemical dosing systems based on conductivity setpoints. Compatible with standard conductivity sensors and suitable for USP 25 compliance when ordered in uncompensated models.
