Only when the pH value in the aquarium is right, the fish develop optimally. In order to maintain the health of plants and fish, the pH, which determines the basic or acidic character of the water, must be checked regularly. Ideally, the pH monitoring is a continuous process, because if the pH value is not optimally adapted to the inhabitants of the aquarium, this can result in stress and illnesses. The pH value of the water can be determined particularly comfortably and precisely with the aquaristics pH meter from PCE Instruments. The aquarium pH meter with monitor is a precision measuring instrument that has been specially designed for the long-lasting and at the same time easy monitoring of the pH value. The measuring range of the aquarium pH meter includes pH values from 0.00 to 14.00.
