PH Maintenence

Hands-free monitoring and dosing of solution pH levels. Simple.

We know pH levels can be the difference between a great crop and well, a disaster. Measuring and adjusting nutrient solution levels constantly can be time-consuming. And let’s face it; you have better things to do.

Our clever pH controller automatically monitors and fine-tunes the pH levels for you. You simply set it, and forget. The pH is taken care of. So you can relax…

The Autopilot pH-1 controller accurately and reliably measures and controls the pH of any water-based solution, including hydroponic nutrient mixtures, and fish aquarium water. After selecting the desired pH setting from 5.0 to 8.0 pH, the pH controller measures the pH value of the solution and automatically adds pH adjustment (either acid or alkaline) to change the liquid's pH to the selected level. The pH controller includes a chemically resistant low voltage dosing pump, and both pH, and temperature sensors. Features include a digital display, adjustable dosing time, adjustable mixing time, adjustable pH dead band, maximum number of dosing cycles, pH high and low limits, and a data logger which shows the minimum and maximum pH recorded. Never before has there been a pH controller with these features for this value. Get automated, get Autopilot! Learn More

Better crops start with the Bluelab Combo Meter, it's all you need for simple and reliable crop management and it's all within arms reach. It is a conductivity, pH and temperature meter all in one. It comes with a pH probe and conductivity/temperature probe, which are simply placed into the solution and the selected reading is displayed on screen. As the Bluelab Combo Meter is portable and does not require a power supply to operate, it can be used anytime and anywhere to help you manage your crops daily nutrient requirements. Calibration of the pH is very easy, using the push buttons on the meter and fresh Bluelab calibration solutions. Conductivity and temperature do not need to be calibrated as this is locked in during manufacture. The Bluelab Combo Meter gives you the added benefit of being able to select the display options for °C or °F and EC, CF or ppm 500. Learn More

Designed for continuous monitoring of pH, TDS and temperature, the HI 981504 is simple to install and can be placed above the sample to be tested. pH, TDS and temperature measurements are simultaneously displayed on three backlit LCDs which can be easily viewed at a distance - even in low light. This means no more switching between parameters. Learn More

pH electrodes are commonly designed to produce and output signal equal to 0 mV when immersed in a solution with pH 7. But a constant output value at pH 7 occurs as a result of certain adverse events, such as: A broken bulb in the pH electrode, A short circuit in the cable or connector, or Magnetic force leakage in the cable or connector (for example, in case of excessive humidity).
