Testo provides unique models for measuring the pH values of various items. The measurement tools are available in many designs that can check the pH levels of solids, liquids, and semi-solids. In addition, the display screen is big enough for people to make a note of the measurements.
The pH meters are electronic devices with a special sensitive measuring probe attached to the electronic meter that displays the decimal reading on the screen. Testo calibrates the device to provide quality results.
A pH meter is used to measure the accurate value of pH, which determines if the substance is acidic or alkaline. The instrument works by measuring the hydrogen activity in the substance, in short, the alkalinity and acidity of the item. The hydrogen ion activity is expressed in pH level.
If the pH solution of an item is less than seven, then it is acidic; else, if the value is greater than seven, then it is basic. A value equal to seven is a neutral item.
