Leybold’s indirect pressure measurement gauges determine pressure based on gas properties such as thermal conductivity and ionization, making them suitable for wide‑range vacuum measurement. The range includes THERMOVAC TTR Pirani gauges, PENNINGVAC PTR cold cathode gauges, IONIVAC ITR active gauges, passive gauges, & more, covering conditions from rough to high vacuum.
These solutions are well suited for continuous monitoring, pump control, and system protection across varying pressure regimes. Selecting the appropriate measurement principle ensures seamless coverage without gaps, supporting stable system control in applications such as vacuum coating, semiconductor processing, and analytical systems.
