Milwaukee MC745 Automatic EC Regulator (Two Pumps)

Product detailed description

The Milwaukee MC745 automatic EC regulator is a device especially appreciated by professional growers. The device continuously monitors the electrical conductivity of the nutrient solution, and if the value is lower than optimal, it automatically adds fertiliser directly into the tank. The EC will return to optimal, and the plants will always have access to the right amount of nutrients.

It uses two pumps to dose the fertiliser - ideal for growers who use A+B fertilisers!

Key features:

• Automatic EC regulation for (nutrient) solution tanks
• Highly accurate measurements
• Designed for the included pumps
• The electrode is on a 2m long cable
• Powered using 12 DVC adaptor
• Large LCD screen and visual LED alarm
• Easy to calibrate
• The set includes an installation kit

Why is it important to monitor the electrical conductivity (EC) of the nutrient solution?

Electrical conductivity tells us how saturated the nutrient solution is. If the EC is too low, it's necessary to add more fertiliser, and when it's too high, it has to be diluted by more water. Incorrect EC values mean over-fertilising or malnutrition - both can endanger plant health and development. Irrigation water, the basis of the nutrient solution (tap water, rainwater, water from a well), can differ in the number of dissolved minerals, which impacts the resulting EC.

EC fluctuates more in recirculation systems than in run-to-waste systems. Measure only after stirring the solution thoroughly to avoid inaccuracies. The correct concentration of nutrients is vital during the entire growth cycle. Please keep in mind that every plant needs a different EC, and every fertiliser has a different impact.

How to calibrate and maintain Milwaukee EC monitors:

Always read the user manual, which describes how to properly use, calibrate and clean the device. You can significantly increase the lifespan of the device by using high-quality buffers, storing and cleaning solutions. We recommend calibrating the device at least once a month. Use a sterile buffer for each calibration.

Protect the device from mechanical damage. If it's not waterproof, keep it away from water, moisture and dust. The warranty on the probe is valid for 6 months from the date of sale! For other components, it's 24 months from the date of sale.

We recommend using the Milwaukee Calibration Solution EC 1,413 mS/cm to calibrate the device.
