Cold cathode gauges

The IKR 270 compact cold cathode gauge measures vacuum from 10-2 to 10-11 mbar. The electronics and gauge sensors are integrated into one compact head. The gauges are metal-sealed with a DN 40 CF flange. The standard version can be baked to 250?C with the electronics removed, and an extended body version is available that allows the gauge to be baked to that temperature without removal of the electronics. The gauges have no filaments to burn out, they can withstand air inrush, and they are corrosion-resistant.
