The Baratron® D28F Dual-range Manometer, an application-specific absolute capacitance manometer features two distinct measurement outputs to provide accurate, reliable, and repeatable pressure measurements for multi-step processes. The D28F is temperature controlled at 100°C, with full scale ranges of 1, 10, 100 and 1000 Torr, with a customer specified second output having either a 2, 5, or 10 times lower full scale pressure output to provide a proportionally higher sensitivity.
