The contact angle Price | ShengDing instrument (certified) | contact angle provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) is specialized in the "contact angle measurement, tensile tester, drop angle detector, tables, interface instrument" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. We all know how much sports contact angle measurement, here to tell you about five technical parameters of kinematic viscosity tester: 1. kinematic viscosity measurement range: 0.5 ~ 20000mm2 / s; 2. Display: 5-inch color LCD, Chinese menu, Touch screen control; 3. Temperature range: room temperature ~ 150 ℃ (if the set temperature is above 100 ℃, in the medium additive); 4. Temperature accuracy: ± 0.01 ℃; 5. dynamic viscosity measurement range: 0.3 ~ 40000mPa.s. INCIDENCE (static light scattering) in the static light scattering particle size analysis method, the contact angle of the factory when the particle size large light wavelength, g before use Fraunhofer diffraction measurement to the small angle region of scattered light intensity to determine the particle size distribution. When the particle size is similar to the wavelength of light, use Mie theory is corrected using spectroscopy. Laser particle size analysis based on both theoretical principles have been applied in actual production. Works on Fresnel diffraction theory as a guide to achieve particle size measurement is in the near field (relative to the Fraunhofer diffraction) detection of diffracted light factory sales contact angle parameters and calculate the particle size distribution, the method has a theoretical Feasibility contact angle retail, for the realization of laser particle size analyzer miniaturization is a good solution. Mature laser diffraction particle size analysis is based on Fraunhofer diffraction theory developed. 1976, first proposed measurement method based on laser particle Fraunhofer diffraction theory, the principle is measured by a laser particle will appear Fraunhofer diffraction, diffraction of different size particles produced with the distribution of angles and different, diffracted by the diffraction energy distribution and the response of the particles after the laser can be calculated according to the particle size distribution of the particles of the sample. Subsequently, a number of countries have developed based on this principle of laser particle size analyzer. According to Fraunhofer diffraction theory designed laser particle size analyzer measurement range of 3 ~ 1000? M.
