Soil pH detector is a device that measures the acidity or alkalinity of soil. The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic, while a pH above 7 is alkaline.
The ideal pH for most plants is between 6.0 and 7.0. However, some plants prefer a more acidic or alkaline pH. For example, blueberries prefer a pH of 4.5 to 5.5, while rhododendrons prefer a pH of 5.5 to 6.5.
There are a few different types of soil pH meters available ：
digital meters, paper strips, and litmus paper. Digital meters are the most accurate, but they can also be the most expensive. Paper strips and litmus paper are less accurate, but they are also less expensive.
