The constant temperature and humidity test chamber consists of two parts: temperature adjustment (heating, cooling) and humidification. Through the rotating fan installed on the top of the box, the air is discharged into the box to achieve gas circulation, balance the temperature and humidity in the box, and the data collected by the temperature and humidity sensors built in the box are transmitted to the temperature and humidity controller (micro Information processor) performs editing processing, and issues temperature and humidity adjustment instructions, which are completed by the air heating unit, condenser tube, and heating and evaporation unit in the water tank. Therefore, the constant temperature and humidity test chamber can accurately simulate the complex natural environment such as low temperature, high temperature, high temperature and high humidity, high temperature and low humidity.
Salt spray test machine
Salt spray test is an environmental test that mainly uses artificial simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials.
The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume space-the salt spray test box, and use artificial methods in the volume space to create a salt spray environment to assess the quality of the salt spray corrosion resistance of the product . Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several or tens of times the salt spray content of the general natural environment, which greatly increases the corrosion speed. The salt spray test is performed on the product and the result is obtained The time is also greatly shortened. For example, if a product sample is tested in a natural exposure environment, it may take 1 year for its corrosion, while the test under artificial salt spray environment conditions requires only 24 hours to obtain similar results.
The salt spray test standard is a clear and specific stipulation for the salt spray test conditions, such as temperature, humidity, sodium chloride solution concentration and pH value, etc., and also puts forward technical requirements for the performance of the salt spray test chamber. The methods for judging the results of the salt spray test include: rating judgment method, weighing judgment method, corrosive appearance judgment method, and corrosion data statistical analysis method. The products that need salt spray test are mainly some metal products, and the corrosion resistance of the products is investigated through testing.
Fast LED spectrum analysis system
The LED spectrometer is used to detect the CCT (correlated color temperature), CRI (color rendering index), LUX (illuminance), λP (main peak wavelength) of the LED light source, and can display the relative power spectrum distribution graph, CIE 1931 x,y chromaticity coordinate graph, CIE1976 u',v' coordinate map. Used with integrating sphere.
The integrating sphere is a cavity sphere coated with a white diffuse reflection material on the inner wall, also known as a photometric sphere, a luminous sphere, etc. One or several window holes are opened on the spherical wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface, and it is usually required that its deviation from the ideal spherical surface should not be more than 0.2% of the inner diameter. The inner wall of the ball is coated with an ideal diffuse reflection material, that is, a material with a diffuse reflection coefficient close to 1. Commonly used materials are magnesium oxide or barium sulfate. After mixing it with a colloidal adhesive, spray it on the inner wall. The spectral reflectance of the magnesium oxide coating in the visible spectrum is above 99%, so that the light entering the integrating sphere is reflected multiple times by the inner wall coating to form a uniform illuminance on the inner wall. In order to obtain higher measurement accuracy, the opening ratio of the integrating sphere should be as small as possible. The opening ratio is defined as the ratio of the area of the sphere at the opening of the integrating sphere to the area of the entire inner wall of the sphere.
