A pH meter is an electronic device used in bonsai for measuring the pH level(acidity or alkalinity) of potting soils. A pH meter usually consists of a probe connected to an electronic meter that measures and displays the pH reading.
There are many different models, some of which are "dual probed" to allow measurement of temperature also.
The PH level of soil can also be measured using a commercially available chemical kit from most garden centres.
