Cool Drawer Dual Sensor
The Cool Drawer Dual Sensor is designed for use in critical processes where it is desirable to have a second crystal in the vacuum chamber. Water cooled, cast stainless steel sensor body, two Cool Drawer crystal holders and a pneumatically actuated shutter provide for a rugged sensor head with the extra reliability of a backup crystal. A cleaner, more reliable vacuum system installation is possible as there are no coaxial cables inside the chamber.
