Benchtop Lab pH Meter mV Tester With Temperature Display 0 to 14.00pH

Description

Benchtop Lab pH Meter mV Tester With Temperature Display 0 to 14.00pH
Overview
PHS digital acidity meter is a high-precision laboratory pH measurement instrument. It has dual functions of pH and MV. E201 composite electrode is used for fast response and good stability. This series of instruments is widely used in many disciplines and fields such as scientific research, teaching, agriculture and so on.
Working principle The activity of hydrogen ions in an aqueous solution is converted into electrical energy by a sensor (pH composite electrode) and input into the instrument. After operation, discharge and detection, the A/D is converted into a digital display. The above electrical energy conforms to the NelnST equation:
