Water Analyzer Equipment

Zetian Group offers a variety types of water analyzer equipments, the major types of water analyzer equipments includes:

Water Analyzer Equipment -- Electrolysis

This kind of water analyzer equipment is composed of a glass cylinder and two parallel electrodes. The electrode material is selected according to the specific application (usually made of platinum or rhodium wire), and a thin layer of H3PO4 is coated between the two electrodes. The electrolytic current between the two electrodes decomposes the water in the acid into H2 and O2. This principle can be used to measure gases, including Cl2, HCl, H2S, H2SO4, HBr, SO2, SF6, CO2 and all inert gases, except for a few gases that react with phosphoric acid.

Water Analyzer Equipment -- Resistance capacitance method

The surface of a high purity aluminum rod is oxidized into an ultra-thin alumina film, which is coated with a porous gold film. The capacitance is formed between the gold film and the aluminum rod. Due to the water absorption characteristics of the alumina film, the capacitance value changes with the amount of water in the sample gas. The humidity of the sample gas can be obtained by measuring the capacitance value.

Water Analyzer Equipment -- Cold mirror method

Let the sample gas flow through the condensing mirror of the dew point cold mirror chamber, and make the sample gas reach the saturated condensation state through isobaric refrigeration (there are droplets on the condensing mirror). The temperature of the condensing mirror at this time is the dew point of the sample gas.

Water Analyzer Equipment -- Optical fiber method

This technology is a new measurement technology developed at the end of the 20th century, which has raised the technology of micro water analysis to a new level. The surface of the water analyzer equipment is a laminated structure of silicon oxide and zirconia with different reflection coefficients. Through advanced thermal curing technology, the pore diameter of the sensor surface can only be penetrated by 0.28-0.3nm water molecules.

The controller emits a beam of near infrared light of 790-820nm, which is transmitted to the sensor through optical fiber cable. The water molecules entering the sensor will change the reflection coefficient of light, which will cause the change of wavelength, which is proportional to the moisture content of the medium. By measuring the wavelength of the received light, the dew point and moisture content of the medium can be obtained.
