Product Description

 

1. Product Introduciton of PH Meter PHS

 

Digital PH meter model PHS-3C is a high-precision instrument for measuring PH of aqueous solution in laboratory. It is mainly composed of main engine, composite electrode, bracket and power supply, etc. This instrument has PH and MV two functions, adopts E201 composite electrode with fast reaction and good stability features.

 

2. Working principle of PH Meter PHS

 

The sensor convert the activity of hydrogen ions in aqueous into electric energy, electric energy in input to the instrument, after operational amplifier and current detection, it is converted into digital display by AD.
