The Pfeiffer PKR 360 is a FullRange® Pirani cold cathode gauge that provides optimal measurements in the range of 1x10^-9 to atmosphere. The PKR 360 features two measurement circuits: Pirani and Cold Cathode. The Pirani circuit is active at all times and the cold cathode circuit becomes active after passing the 1x10^-1 Torr threshold, providing a full range of measurement and allowing for use in a wide variety of applications. Vacuum pressure can be displayed via a DCU or Pfeiffer TPG 361 Vacuum Gauge controller. The gauge can not be used for the measurement of highly flammable or combustible gases in the mix-ture with an oxidizing agent (e.g. atmospheric oxygen) within the explosion limits
