Thermocouple For Wafer

Sapphire Crystal Window Sapphire windows are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; high-durability windows and movement bearings;Due to sapphire's remarkable hardness (third hardest mineral, right behind diamond and moissanite). Features of Sapphire Crystal 1. High-hardness - abrasion resistance 2. Transparency - in the range from ultraviolet to infrared light (0.15 - 5.5 �µm) 3. Chemical resistance and heat resistance - resist almost all kinds of acid and alkaline, heat up to 2000 �ºC. 4. Suitable for the application of insulation property required.

What is oxy-hydrogen generator: Oxy-hydrogen generator/hydroxide generator can set fire to water by electrolyze water into hydrogen gas and oxygen gas. We can use H2 and O2 as the fuel of flame replacing LPG, propane, acetylene fuel, natural gas or others. gas pressure. The gas output volume is adjustable. Easy to operate. 2. Cost saving: Oxy hydrogen Generator saves 60% cost compared to acetylene. Saves 40% compared to propane. 3. Welding quickly The oxy-hydrogen flame calorific value reaches 34000Kcal/kg, and temperature high up to 2800 degree. It can make the welding spot reaches melting point in 1 second. 4. Welding precisely: The flame is concentrated, it can achieve welding precisely. 5. Clean flame without carbide: Oxy-hydrogen flame combustion doesn't form any carbide, so there is no black spot after welding. And it will not influent the rigidity & flexibility of workpiece. 6. Environment friendly: Oxy-hydrogen generator just needs pure water & electricity as fuel. And it will just generate steam in the end. Do no harm to environment. Application: 1.
