The MKS Instruments PDR2000 is a dual-channel digital power supply and readout unit engineered to power MKS Baratron® capacitance manometers and display pressure measurements with high precision. The instrument delivers ±15 VDC @ 750 mA per channel and features a 4-digit red LED display with selectable engineering units (Torr/mTorr or mbar/microbar). Two fully programmable process relay trip points with independent hysteresis control enable automated setpoint management across measurement ranges spanning 0.01 mTorr to 10.00 kTorr.
