Type PBMS2B
TWO-CHANNEL PORTABLEt BARATRON® MEASUREMENT
SYSTEM
Designed with the cleanroom in mind, the PBMS2B is a portable two-channel pressure
standard that is designed for in situ applications. Equally at home on the bench as on the
production floor, the unit may be used for any pressure measurement application in the
range of 10-5 to 1000 Torr.
The system includes one or two Type 627B Baratron capacitance manometers, a Type
PDR2000 display and an uninterruptable power supply all housed in a rugged wheeled
caddy with an extendible handle for easy towing. The caddy also includes an integral tilt
stand which, when extended, places the unit at an angle of 15 degrees from the vertical,
thereby improving visibility of the display when the unit is on the floor.
