Low Pressure Measurements

This course covers the principles, techniques, and applications of low pressure measurement devices, specifically focusing on the McLeod gauge, Pirani gauge, and ionization gauge. For instance, learners will explore the operational principles of these gauges, how they measure extremely low pressures, and the potential sources of error in these measurements. The course also delves into the steps to follow when using a McLeod gauge, the limitations of the Pirani gauge, and the working principle of the ionization gauge. Additionally, the course discusses pressure measurement using probes, highlighting the advantages of using probes and the differences between 3-hole and 4-hole probes in fluid mechanics.
