Introduction An integrating sphere is a spherical device used to measure the optical properties of materials. It is a hollow sphere coated with a highly reflective material on the inside surface. The sphere is designed to uniformly distribute light from a source to the sample and collect the reflected light from the sample. Integrating sphere are used in a wide range of applications, including lig...
The ozone aging test chamber is suitable for temperature resistance testing of non-metallic materials, as well as ventilation aging testing and inspection of electronic component parts and molten goods. It can be used to vulcanize rubber products such as rubber materials, thermosetting plastic vulcanized rubber, cable insulation sheaths, and other products, exposed to closed type under static ten...
Flush receptacles The grounding terminal of a grounding-type flush receptacle shall be spaced at least 1/4 inch (6.4mm) from any ungrounded live part (associated with other than a white grounded terminal) exposed to contact by a grounding conductor in the outlet box. Live parts accessible from within the cavity of an outlet box are considered exposed to contact by a grounding conductor if they can...
IPX9K High Temperature Pressure Jet Waterproof Test Chamber is a test equipment specially used to simulate extreme environmental conditions in industries such as automobiles, aerospace and ships. The test chamber has the characteristics of high temperature, high pressure, high humidity, etc., and can simulate working conditions in extreme weather and harsh environments to ensure product quality a...

The key of the sand and dust test chamber is to simulate the damage of win...
9.1 General 9.1.1 A device shall have live parts protected against exposure to contact by persons when fully assembled using all essential parts (described in 9.1.5) and installed in the intended manner. Exception No. 1: Male blades which are energized only when mated with the corresponding outlet are not required to comply with this requirement. Exception No. 2: Exposed wiring terminals or other ...
Colorimeter is also called portable colorimeter, color analyzer and color colorimeter. The colorimeter is a simple color deviation testing instrument, that is, to make a filter that simulates the spectral characteristics equivalent to the color sensitivity of the human eye, and use it to measure the light of the sample plate. The key is to design the spectral sensitivity characteristics of this ph...
Isolation transformer is a special type of transformer, which has its input and output winding connected in an electrically isolated fashion, mainly used in occasions with reverse phase separation, to realize electrical isolation and simultaneous voltage step-up/down. The main application of isolation transformer is to electrically isolate two related circuits, usually applied in electronic indust...
