The GZK-PID-103G-LD is a highly sensitive, compact and PID-controlled vacuum pressure regulating system. The system consists of a mechanical pump and a turbomolecular pump, allowin g two different working modes: 1) achieve a high vacuum environment by the turbopump; 2) control the output of gas flow by the mechanical pump and the PID system to keep the pressure at a constant level. This system comes with a pressure measuring transducer for precise pressure monitoring. The system is compatible with MTI furnaces to achieve ideal pressure conditions for PVD, CVD, PECVD and HPCVD processes. This system has been widely used for applications such as diffusion, oxidization, expitaxy, CVD, plasma sputtering, coating and optical fiber melting.Specifications Power Requirement 208 ~ 240 VAC, single phase, 50 ~ 60 Hz.
