The MKS HPS® Series 999 Quattro™ is the ultimate transducer solution, providing pressure measurement from 10 Torr to atmosphere, combined with atmospheric switching capabilities. The Quattro combines three of HPS' key technologies into an integrated gauge solution, and has the functionality of four sensors in one compact package. The Quattro includes the miniaturized hot cathode ionization sensor, the MEMS-based MicroPirani™ sensor and a unique piezo sensor, offering both differential and absolute sensor functions. Customers requiring both a power supply and display can use the 999 with the PDR900 Series Controller sold on this website. For Complete Specs and Operation Information see the DOWNLOADS section.

The MKS The PDR900 power supply and readout unit is a stand alone, single channel controller for use with the Series 900 digital vacuum transducers. The instrument sets new standards for vacuum gauge controllers and can be used as a stand-alone power supply readout unit or as a tool for configuration, calibration and diagnostics of system integrated transducers in OEM applications. The PDR900 controller is the ideal solution for vacuum measurement, configuration of digital transducers and advanced system diagnostics. The controller features an easy to use menu-driven user interface, which guides the user through setup and configuration of remote transducer parameters. The readout unit communicates digitally with the transducer which eliminates analog measurement noise coupling via transducer cables. The unit automatically detects the 900 series transducer types, and can be used with both RS232 and RS485 transducers (Not compatible with 909/909A or 903 analog transducers).
