The StrataVac is one of DigiVac's leading products for customers looking to both measure and maintain pressure. It is a more complex device that offers a number of different configurations, making it possible for every customer to get exactly what they need.
One of the unique features of the StrataVac is that in addition to having the ability to communicate the pressure that your system is maintaining, the gauge can be ordered with a regulator card and valve which opens and closes as needed in order to control your system at a specific pressure, for example, 2 Torr. This configuration of the gauge which gives you the ability to control, is useful for those conducting experiments that require consistent pressure readings. It is also a common request for those who work in industries where processes require stable pressure to ensure that the final product was held to a particular vacuum level during a process, an example being the StrataVac maintaining a predetermined pressure in a chamber that is vacuum drying products for the medical industry.
Having compatibility with capacitance manometers gives you another configuration to look for. With the use of a capacitance manometer that measures a specific pressure with more reliable accuracy than a thermal sensors, you can more easily control your system at a pressure that is suitable for your experiment. This pairing of the StrataVac and capacitance manometer is often utilized by those in labs doing research, as a calibration standard for other instruments, or as an in-house standard when performing tests. It seems that many in the vacuum field choose capacitance manometers whenever possible because it is isolated and particles cannot contaminate the sensor.
Vacuum Controller - Drive and combine up to 3 of your sensors | Save space, money, and avoid confusion by combining multiple tasks into one device. Can control vacuum with bleed or throttle valves from 10mT - 760T.
Modular - Can be configured with up to 4 expansion boards to control multiple gauges at one time | Accepts different inputs based on driver board and sensor election | Possible different outputs including: analog recorder, RS232, Ethernet, SPDT relays and VLC
