Myron L (758II-122) 0-2,000 PPM Dig. Monitor-Control
758II-122 Digital Conductivity Monitor/Controller
Continuous Measurement and Control
Conductivity Sensing
Sensor input continuously measures electrical conductivity from 0 to 2,000 PPM with automatic DC offset compensation to eliminate electronic drift over time.
Temperature Compensation
Precision TC circuit adjusts readings as water temperature changes, perfectly matching the water temperature coefficient and correcting all values to 25°C reference.
LED Status Display
Green and red LEDs indicate whether readings are above or below programmed set point. Push-to-test button allows instant verification without disrupting operation.
Relay Automation
Heavy-duty 10 amp relay switches on either increasing or decreasing conductivity readings to trigger valves, pumps, or alarms based on water quality thresholds.
Technical Details
| Model Number | 758II-122 |
| Measurement Range | 0-2,000 PPM (TDS) |
| Temperature Compensation | Automatic to 25°C |
| Relay Output | 10 amp SPDT |
| Enclosure Rating | IP64 / NEMA 3 |
| Dimensions | 6 x 4.8 inches (152 x 122 mm) |
| Mounting Options | Panel, bench, or surface |
| Alarm Protection | Internal set point lock |
System Integration
The 758II-122 accepts standard conductivity sensor inputs and mounts in any orientation within splash-prone industrial environments. Optional accessories include a 3-sensor input module, 3-range switch for expanded measurement flexibility, and remote alarm output. The relay can trigger solenoid valves, chemical dosing pumps, or annunciator panels in RO systems, boiler feed lines, cooling towers, and aquaculture operations requiring automated TDS control.
