Product details

1、 The purpose of the instrument

The PHB-4 portable acidity meter is a 31/2-digit LCD digital display acidity meter (hereinafter referred to as the instrument). The instrument is suitable for sampling and measuring the acidity (pH value) and electrode potential (mV value) of aqueous solutions in laboratories such as research laboratories, pharmaceuticals, factories, chemical engineering, environmental protection, and mining sites. It is easy to carry and not only practical for laboratories, but also for field production sites. If equipped with appropriate ion selective electrodes, it can serve as a terminal indicator for potentiometric titration analysis.
