MPCVD single crystal diamond growth machine equipment
Microwave plasma chemical vapor deposition (Microwave Plasma Chemical Vapor Deposition) is the preferred method for the preparation of diamond with high efficiency and high quality, which breaks the limitation of equipment on substrate size and provides conditions for the growth of large area single crystal diamond.
Standard Leak and Reference for Calibration Specification of Differential Pressure Airtight Leak Detector
Tightness leak detector calibration leak VTL-DA type (Air)
Air tightness leak detectors generally have direct pressure type, differential pressure type and flow type, etc. The detection system forms a pressure difference under vacuum or positive pressure conditions, and calculates the leakage by judging the change of pressure or flow.
