pH meters are essential for measuring the acidity or alkalinity of water and other liquids. In Kenya, where agriculture, water safety, and industry play a big role in daily life, having a reliable pH meter is a must.
What is a pH Meter?
A pH meter is a digital or analog device used to measure the hydrogen-ion activity in a solution, indicating its acidity or alkalinity on a scale of 0–14. It’s far more accurate than pH strips and is commonly used across various sectors in Kenya.
Why Water pH Testing is Crucial in Kenya
From borehole water testing to farming, accurate pH levels ensure safety and effectiveness. Drinking water, for example, should ideally have a pH between 6.5 and 8.5.
