Water Quality Sensors

Instrument Features
The unique design makes this product have lower failure rate, lower maintenance, lower reagent consumption and higher cost performance than similar products.
Select valve assembly: select the reagent sampling sequence, the channels are flexible and diverse, the functions are changeable, and it has the advantages of minimum dead volume, easy maintenance and long life.
Micro metering component: The precise metering of reagents is realized through the visual photoelectric system, which overcomes the quantitative error caused by the wear of the peristaltic pump tube; at the same time, the precise quantification of micro-reagents is realized, and each dose is only 1 ml, which greatly reduces the use of reagents quantity.

Basic Principles of PH Electrodes
The electrodes used in pH measurement are also known as galvanic cells. A galvanic cell is a system that converts chemical energy into electrical energy. The voltage of this battery is called the electromotive force (EMF). This electromotive force (EMF) consists of two half-cells. One of the half-cells is called the measuring cell, and its potential is related to a specific ionic activity; the other half-cell is the reference half-cell, usually called the reference electrode, which is generally connected to the measuring solution and is connected to the measuring instrument.
