Renk Mukayese Ekipmanları

        The cabinets come supplied with different lights and are controlled by a microprocessor LCD Screen that shows each Lighting usage Time. Each Button controls the individual set of Lights. The CLR（Clear）button allows the resetting of the Lighting Usage Time to ZERO when new lights are replaced. The ON/OFF Switch button must be switched off during long hours（more than 3 to 4 hours）of non-operation. This is to reduce the possibility of heat-up as well as to increase the life span of the electronic ballast. All Lights can be switched on at the same time as according to the user needs. The optional Diffused Glass Panel below the lights ensures the elimination of direct reflection of lights to viewing products, There is no Warm-Up time/Flickering of Lights when there is a constant electrical supply. All electrical components used are of low power consumption and heat generation for energy efficiency in .

        The international approved Light Gray Non-Reflective Surface ensures that no light is being reflected from the surface during color matching, so, what you see of your products in our Biuged Color Assessment Cabinets will be as natural as what you view them under the natural color matching conditions. The Non-Reflective Surface has certain degree of roughness not only acts as light absorption when light are illuminated, but it is also scratched-resistance, Many Color-Matching Cabinets do not have this dual ability.

Iron-cobalt Color Comparison Tester

        It is designed to measure the color of the varnish ,thinner and other transparent liquids.

        Take a certain amount of ferric chloride hydrochloric acid solution, potassium dichromate sulphuric acid solution, and cobalt chlorite hydrochloric acid solution, The above three solutions will be mixed together at a certain percentage in order to get 18 solutions with different colors and densities. Then put them into the tubes and sealed separately.

        The visual method is used to assess via the comparison with a series of anvil standard tone scale solution，which is marked with the color gradation number. The result is shown in 1-18.

Main Technical Parameters

■ Colorless glass tube with the internal diameter of Φ10.75±0.05mm,and the height of 114±1mm.

■ Color comparison box(self-prepared)

■ The test must be taken at the temperature of 23±2℃

Gardner Color Comparator with C Illuminant


 

        Colour variations of transparent liquids such as varnishes, solvents, resins, tensides, oils et.,may be caused by contamination or impurities, process inconsistencies, or excessive weathering.Therefore,reliable and accurate measurements are essential to ensure consistent production standards.

        BGD 425 Gardner Color Comparator with C Illuminant is used to test the color of drying fatty oil, varnish, fatty acid, polymerized fatty acids and resin. It complies with ISO 4630 standard.

Main Technical Parameters
■ Working Standard：18 pcs different standard liquid color which are prepared according with ISO 4630
■ Glass tubes：Colorless and transparent with inner diameter is 10.65± 0.025mm,external diameter is 12.5mm and the length is 114mm
■ Illuminant：Its energy of spectra is similar with C light resource of CIE. And the ray come through breadth wise the working standard color and sample
■ The environment is neutral color, the two working standard colors and one sample are within eye shot

DİJİTAL ABBE REFRAKTOMETRE


 

  A refractometer measures the extent to which light is bent （i.e. refracted） when it moves from air into a sample and is typically used to determine the index of refraction （aka refractive index or n） of a liquid sample.
        The refractive index is a unit-less number, between 1.3000 and 1.7000 for most compounds, and is normally determined to five digit precision.     
       The refractive index is commonly determined as part of the characterization of liquid samples, in much the same way that melting points are routinely obtained to characterize solid compounds. It is also commonly used to：
         * Help identify or confirm the identity of a sample by comparing its refractive index to known values.

         * Assess the purity of a sample by comparing its refractive index to the value for the pure substance.

         * Determine the concentration of a solute in a solution by comparing the solutions refractive index to a standard curve.

      BGD 252 Digital Abbe Refractometercan be used widely in petroleum, chemical, pharmaceutical, sugar refining and food industries,as well as in related colleges,universities and scientific research institutions for measuring the refractive index nD of transparent of sub-transparent liquid,or solid substance.it also can be used to measure the Brix(BX) of the sugar solution,and to correct the affect of temperature on the Brix automatically. 
        ◆ Visual aim and LCD display 
        ◆ Correct automatically effection of temperature on the Brix.
        ◆ Prism is made of hard glass
        ◆ RS232 interface
