Bluelab pH Dosing Kit
The Bluelab pH controller allows hands-free monitoring and dosing of solution pH levels.


pH levels can be the difference between a great crop and a disaster. If the pH is consistently out it can lead to plant deficiencies an even slower growth rates. Measuring and adjusting nutrient solution levels constantly can be very time-consuming. The controller automatically monitors and fine-tunes pH levels. It needs only to be set up correctly and the pH is taken care of.


Before use it’s important to soak the probe in some KCL solution. This will hydrate the probe and help with longevity. Never let the probe dry out and when not in use add some storage solution to the cap to stop this happening. The new probe with need calibrating with two Buffers, normally 4 and 7. Do this before using and when obtaining a reading try not to put the probe where water might be coming back into the tank from a pump or where it will get in the way when you are mixing the nutrient solution. 

The Bluelab pH Probe is easy to clean because of its bullet shaped glass bulb, fully waterproof and less fragile than all-glass electrodes because of its tough polypropylene barrel. The pH probe is gel filled (non-refillable) making it maintenance free and has a double junction reference which provides longer life.
