Mounted in a sturdy transportable cart, the PVS6E provides NIST traceable calibrations over the pressure range from 10-5 to 1000 mmHg and can be used to calibrate capacitance manometers, thermocouple gauges, Pirani gauges, convection enhanced Pirani gauges, other capacitance manometers and transmitters, and mechanical/dial gauges.
The PVS6E pumping system consists of an air-cooled hybrid turbomolecular pump, backed by a two stage diaphragm pump. A high vacuum gauge is provided to monitor system performance and base pressure to ensure pressure is low enough for proper zeroing of the transfer standards. The PVS6E is available with manual pressure control capability. The PVS6E has an uninterruptible power supply with sufficient storage to keep the transfer standards warmed up and ready to use for up to 60 minutes, allowing ample time to transport the PVS6E to the process system. The PVS6E can perform off-line as well as in situ calibrations.
