Bluelab pH Pen: Handy, light & practical. A pH meter for all plant-lovers and for many other uses among hobby gardeners.
The Bluelab electronic pH meter enables uncomplicated testing of the optimal pH value of irrigation water both before and after adding fertiliser. The pH value defines how ?acidic? or ?alkaline? a fluid is, i.e. how well other substances can dissolve in it. As such, the fluid should have an ideal pH value so that the added nutrients can dissolve optimally, as they are otherwise inaccessible to the plant. (Roots cannot ?directly? take in nutrients, only in a solution with water).
The pH value of the nutrient solution should therefore always be in the appropriate range for the plant (and adjusted with pH correction solution if necessary), so that all necessary nutrients and trace elements in the nutrient solution can be absorbed.
The Bluelab pH Pen is a quality, microprocessor-controlled, water-resistant pH meter and thermometer. It combines professional name brand quality with a very attractive price.
Measured values are shown on the LCD display and can be saved using the ?hold? function. The pH value is temperature-compensated and measured precisely to one decimal place.
