Overview of Cold Cathode and Pirani Principles Engineers working with vacuum systems in mass spectrometry, vacuum heat treatment, battery manufacturing, or scanning electron microscopy quickly discover that no single gauge covers every pressure decade reliably. The two workhorse technologies—Pirani (thermal conductivity) and cold cathode (Penning discharge)—operate on entirely different physical principles, each excelling where the

Define Application Parameters Selecting the right vacuum gauge begins with a clear definition of your application parameters. Industrial engineers and procurement teams who skip this step often end up with oversized, overpriced, or incompatible instruments that increase downtime and total cost of ownership. Start by documenting the end-use environment, process flow, and performance expectations. Key
