Anionic Surfactant Water Quality Automatic Analyzer

A cationic dye, methylene blue, reacts with anionic surfactants to form a blue salt.

Selenium Water Quality Automatic Analyzer

The water sample, which may contain impurities such as zinc, cadmium, lead, copper, and selenium, can be processed using a membrane electrode as the working electrode in an appropriate supporting electrolyte solution.

Aniline Compounds Water Quality Automatic Analyzer

Aniline compounds react with nitrite under acidic conditions (pH 1.5 to 2.0) to form diazonium salts. These salts then couple with N-(1-naphthyl)ethylenediamine dihydrochloride to form a purple-red dye.

Silicate Water Quality Analyzer

Under acidic conditions, silicate reacts with ammonium molybdate to form silicomolybdenum yellow. This compound further reacts with 1-amino-2-naphthol-4-sulfonic acid to form a blue compound.

pH Sensor

The S310 pH meter, independently developed by BESCIENT TECHNOLOGIES, operates based on the fundamental principle of the glass electrode method.

Temperature Sensor

The S310 thermometer, independently developed by BESCIENT TECHNOLOGIES, operates based on the principle of temperature sensing.

Conductivity Sensor

The S310 Conductivity Meter, independently developed by BESCIENT TECHNOLOGIES, operates based on the principle of electrolytic conductivity.

Dissolved Oxygen Sensor

The S310 Dissolved Oxygen Meter, independently developed by BESCIENT TECHNOLOGIES, utilizes the Clark electrode polarographic cell principle.

Turbidity Sensor

The S310 Turbidity Meter, independently developed by BESCIENT TECHNOLOGIES, operates by emitting light towards the sample using the instrument's sensor light source component.
