Profile: Samit Enterprises is a manufacturer & supplier of laboratory equipment and electronic kits. Our products cater to the needs of colleges, auto ancillaries, rubber industries, and automobile industries. Our auto collimators are used for various kinds of measuring requirements like displacements in linear and small angles, and flatness testing. We offer monochromatic light units which are available with varied specifications and dimensions. For longer life, these are coated with sodium vapor lamp and copper. Scratchless powder coat and milk white acrylic sheet on the steel fabricated box provide uniform intensity. These units are available in different sizes and shapes: such as concave, convex, and optically flat surfaces with tour formation and steel master. Gauge angle valves are used along with a toughened glass tube for liquid level indicator in receivers and accumulators. One pair of valves are used for one set of liquid level indicators. If the glass breaks by some sudden impact, the ball inside the valves stops the refrigerant flow immediately.
