CMCAT1134AR
Brooks Instrument 10 Torr Unheated Capacitance Manometer
About this part
Brooks Instrument CMCAT1134AR is a compact, unheated absolute-pressure capacitance manometer configured for a 10 Torr full-scale range. Its documented configuration includes a 0–10 VDC analog output, 15-pin D-sub connector on a 6-inch cable, 8 VCR female fitting, ±0.25% of reading accuracy, and RoHS compliance. The measurement is independent of gas composition
Configurations vary. Verify the exact unit before choosing a replacement.
