CD611 Milwaukee Eco Ec-meter

The Milwaukee ECO CD611 EC Meter is one of the most affordable devices on the market considering how precise it is. This instrument is something that all growers should have – perfect for controlling EC levels simply and precisely.

These devices are super easy to use, too, allowing you to see if you’re using too many nutrients in your nutrient solution – you’ll be able to avoid situations involving over-fertilization or nutrient deficiencies. Whichever your grow method is, this device will come in handy.

It’s super easy to calibrate; you’ll need to get some EC calibration liquid, EC 1413 to be precise, and use the screwdriver included with the device to adjust it to the same amount as the liquid.

All you have to do is submerge the tip of the sensor in the calibration solution and adjust the screw accordingly. Once it’s been adjusted you can start using the device. Remember to calibrate every now and them.

Ec CD611 operation:

• Remove the black protector and turn it on by pressing the ON/OFF button located at the top.
• Submerge it up to the limit and wait until the meter is stabilized.
• The meter compensates temperature variations automatically.
• After using it, wash the electrode with water to keep it clean.

Calibration:

• Submerge the meter until the limit in Ec calibrating liquid (M10031)
• Wait until the device is stabilized and adjust it to 1.4 with the screwdriver located at the side (multiplying it by 100 equals Ec value =1413).
• The meter is calibrated.
• ALWAYS use new calibrating liquid. Do not reuse the same liquid under any circumstances.
