SGJ611Y-II Color Stability Tester

• SGJ611Y-II Color Stability Tester

  Instrument use:
    It is suitable for testing the color stability of dental materials after exposure to water immersion light.
  Standards compliant:
    YY/T 0631-2008 Dental materials - Determination of color stability; YY0710-2009 7.9 Color consistency and color stability.
  Features:
    1. High-quality medium-pressure long-arc xenon lamp is used to simulate the sunlight spectrum, the service life can reach 1500h, and the spectrum is stable;
    2. The xenon lamp is air-cooled, and the equipment is more compact;
    3. The equipment has automatic shutdown when the door is opened; safety protection monitoring points (irradiance, water level, cooling air, temperature in the warehouse, warehouse door, overcurrent, overvoltage) can realize unattended operation of the instrument;
    4. Adopt high-quality filter, made of optical glass (borosilicate glass), the transmittance for light waves below 300nm is less than 1%, and the transmittance for light waves above 370nm should be greater than 90%;
    5. Ensure the reproducibility of the same environment within the life of the xenon lamp, that is, the color temperature, illuminance, pressure value, filter performance, spot diameter, uniformity, etc. do not change.
    6. During the irradiation test, the irradiance of any position on the exposed surface of the sample shall be at least 80% of the highest irradiance of the exposed surface
    7. Adopt imported temperature controller and timer, stable temperature control and accurate timing;
    8. The xenon light illuminates the entire water tank, and the sample is more uniformly illuminated;
    9. The movable water tank is designed to facilitate the clamping and removal of samples;
    10.Built-in water tank to realize the function of circulating water bath.
