The Bluelabs BLU27100 is an incredibly accurate continuous ph Monitoring device. It gives real-time temperature, pH and EC readings. The monitor comes with a large, easy-to-read LED display. Calibration is quick and easy. Much like the Blue Labs pH monitor it is a reliable lab grade device.

pH is crucial for proper nutrient absorption. For DWC your pH needs to remain between 5.5 and 6.5. I like to mix freshwater batches to pH 5.5 because the trend I have noticed is pH rises as plants absorb nutrients. The plants and roots seem happiest with a low pH.
An EC meter measures Electrical Conductivity to give you a rough measure of the nutrients in your solution. It is only a rough measure because pH up, pH down, minerals from your tap water and minerals the plants deposit into the water will all increase EC. You can get away with not using an EC meter but they make it much easier to top off your water rather than having to do complete water changes each time.
Baseline EC level – When using the chart above remember to subtract the baseline EC level. For example:
Tap water EC = 150
Measured EC = 1550
Actual EC = 1400
PPM is inferred by EC. The general conversion is:
EC * 2 = PPM
Temperature – Monitor your hydroponic temperature to ensure it stays under 70F (ideally under 68F).

Maintenance
Like with all continuous pH monitoring systems it is important to not let the electrode dry out. Use the included cover on the probe when it is not submerged in solution. Store wet (ideally with a slightly acidic solution) and do not let it dry out.
