DOSE. MONITOR. CONTROL. AUTOMATICALLY.
The MC740 kit includes the MC311 EC controller and MP810 dosing pump to automatically monitor and adjust EC levels. Simply set your EC parameters and let the Milwaukee EC controller and pump do the rest.
After selecting the desired EC setting from 0.8 to 2.8 mS, the controller measures the EC value of the solution and automatically adds grow nutrients. Thanks to the small and precise flow rate of the pump, you maintain ideal EC values in your tank.
The MC311 comes with MA9310 12 VDC adapter, MA812/2 EC probe, 20 ml bag of 5000 μS/cm calibration solution, calibration screwdriver and instructions. And the MP810 comes with mounting bracket, screws, 1.5 meters Ext. PE tube, filter, fitting and 2.6 meters power cable.
DESIGN FEATURES
- Quick and easy to read current results with large digital LCD readout and visual LED alarm
- Accurate to ±2% full scale (0.0 pH to 10.0 mS/cm) with user selectable high/low set points
- Simple one-point calibration for greater accuracy with manual trimmers for easy adjustment
- MA812/2 hardwired EC probe included
- 6.5 foot probe cables for added flexibility in testing
- 12 VDC power supply
- Pump delivers a maximum pressure of 1.5 bar or over 50 feet of head with a dose rate of 0.16 GPM.
USE AND MAINTENANCE
EC sensors are more robust, but can still be affected by residue buildup.
EC electrodes may start to release nutrients over time. Rinse the probe with fresh tap water after each use to prevent build-up.
CONVERTING EC TO TDS
The Milwaukee EC controller, like all conductivity meters, provides a measurement of electrically charged ions in a solution and is an absolute measurement of conductivity.
EC is often converted to TDS in parts per million (ppm). There are several scales, such as the 500 scale, the 650 scale, and the 700 scale. However, the true PPM can only be determined by chemical analysis.
Your mS/cm reading can be converted to TDS (ppm) by approximation:
2,000 µS/cm = 2.0 mS/cm = 1000 ppm on .50 factor scale
2,000 µS/cm = 2.0 mS/cm = 1400 ppm on 442 scale or .70 factor scale
