| DVR-300 The
DVR-300 is designed for vacuum systems that run continuously, such
as oil-filled vacuum pumps, aspirators, or with systems that are
"always on", like in-house vacuum systems. When the
DVR-300 is connected between a vacuum source and a piece of
equipment, the vacuum valve inside the DVR opens and closes so as to
regulate pressure inside the attached piece of equipment to within
± 1 mmHg.
DVR-380 The
DVR-380 is designed for use with systems that regulate vacuum by
turning on and off the vacuum pump itself, as is common when using a
diaphragm vacuum pump. The DVR-380 extends the life of
diaphragm pumps by never forcing the pump to start against an
established vacuum, which reduces pump life by over 50%.

J-KEM’s computer (built in) controlled pressure
regulator maintains pressure to better than 0.1 mmHg in equipment as
small as 5 ml flasks. Built from J-KEM’s Infinity Controller (see
page 9), these instruments can be customized to perform user-defined
tasks like adding reagents as a function of pressure and temperature
(call for details). Three regulators are available to precisely
control vacuums, positive pressures, and a combination of the two. |

Description |
| DVR-1000 |
Digital Vacuum Regulator. Precisely
controls vacuums in the range of 0.1 to 760.0 mmHg
(atmospheric pressure). Requires the selection of a PSV
(below) that matches the volume of the system being
regulated. |
| DPR-1100 |
Digital Pressure Regulator.
Precisely controls pressures in the range of atmospheric
pressure to 500 psi. Not for the regulation of vacuums.
The maximum pressure range is user selectable. Replace
the ‘*’ in ‘DPR-1100-*’ with the selected
maximum pressure. Ranges: 15, 30, 60, 100, 200, 300, 500
psi. Requires a PSV (below) that matches the
volume of the system being regulated. |
| DDR-1200 |
Dual Range Vacuum & Pressure
Regulator. Precisely controls
both vacuum and positive pressures. The DDR-1200 is
equipped 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 regulator is user selectable.
Replace the ‘*’ in ‘DDR-1200-*’ with the
selected maximum pressure. Ranges: 15, 35, 85, 185, 285,
485 psi. The DDR-1200 requires two proportioning
valves (below). Both valves connect to the system being
controlled, the first to regulate vacuum, the second
pressure. |
| PSV-2 |
Valve to use when apparatus total
volume is 1 ml to 2 L |
| PSV-3 |
Valve to use when apparatus total
volume is 10 ml to 4 L |
