Add a liter mark to the meter, which counts the liters of water passing through it. For example, if you want to remind you to change filters every 3500 liters, then you will give that reading to the meter. After reading the instructions below, the meter starts counting down the liters until it reaches zero. Once it reaches zero, it starts and whistles to alert you to change your filters.

PH meter measures Ph in your water. It is an ideal instrument if you are an aquarium owner, since fish can only live in a very specific environment.
