Product details
1、 Product Overview
This series of instruments is a pH meter controlled by a microprocessor, selected from integrated components and rigorously screened and refined. It has stable and reliable performance, and is easy to operate. Suitable for precise measurement of acidity (pH value) and electrical potential (mV) of solutions in the laboratory. When combined with ORP electricity, the ORP (oxidation-reduction potential) value of the solution can be measured. When combined with ion selective electricity, the electrical potential value of this electricity can be measured. Suitable for precise measurement of acidity (pH value) and electrical potential (mV) of solutions in the laboratory.
