Quick Overview

J-KEM's vacuum and pressure regulators maintain pressure to 0.1 torr in reactors and equipment with volumes as small as 1 mL.  Built from J-KEM's Infinity Controller, these instruments can be customized to automate virtually any laboratory or quality control task involving the regulation of vacuum or pressure.  For applications requiring both evacuations and repressurization, a Back-Fill option is available for the DVR-1000.  The DVR-1000 regulates vacuums, the DPR-1100 regulates positive pressures, and the DDR-1200 regulates both vacuum and positive pressures.

KEM-Torr software (included) displays a real-time plot of system pressure, implements a 16-step pressure ramp, data logging and remote PC control. Custom features can often be added at no additional charge.


Requires the selection of a proportioning valve


Regulation of both vacuum and positive pressures. The DDR-1200 is built with a dual range pressure transducer capable of accurately measuring pressures from full vacuum to the pressure limit of the transducer selected. The maximum pressure of the controller is user selectable. Requires the selection of two PSV valves, one for vacuum and one for pressure regulation. Contains an absolute pressure transducer. Includes KEM-Torr software to load on your PC.
