The SCSP Pressure Sensors Calibration System is designed for the accurate measurement and calibration of positive and negative pressure. The system enables students and users to perform practical experiments using different pressure and vacuum measuring instruments. It includes two pressure manometers for low and higher pressure ranges, along with two vacuum gauges for measuring negative pressure. A graduated cylinder allows water pressure measurements in millimetres and helps verify the calibration of the system’s manometers. A syringe is also included to generate pressure and vacuum for experimental purposes. The SCSP provides a simple and effective platform for studying pressure measurement techniques and pressure gauge calibration in educational and technical laboratory environments.
