New Touch Gas Purity Moisture and Decompostion Comprehensive Analyzer Made in China

The surface of the fiber optic humidity sensor is a layered structure composed of silicon oxide and zirconia with different reflection coefficients. Through advanced thermal curing technology, the pore size of the sensor surface is controlled at 0.3nm, and water molecules at 0.28nm can penetrate. The controller emits a beam of near-infrared light at 790-820nm, which is transmitted to the sensor through a fiber optic cable. The water molecules entering the sensor will change the reflection coefficient of the light, causing a change in wavelength, which is proportional to the moisture content of the medium.

Another common moisture analyzer is the conductivity analysis moisture analyzer, which places the measured liquid sample in an electrolyte solution and adds an indicator. Under the action of an electric field, ions move and form an electric current. Then, the conductivity of the sample can be determined by measuring the magnitude of the current.
