Inficon BPG 400 Bayard-Alpert Pirani Combination ATM to Ultra High Vacuum Gauge, DN40 CF-R CF 2.75 in Fitting, PN: 353-502

This Inficon Bayard-Alpert Pirani Combination Gauge, BPG400, Model 353-502, functions as two gauges in a single compact unit and measures from 5x10-10 mbar (3.75x10-10 Torr) to atmosphere. The gauge uses a long-life yttrium oxide coated iridium filament and has Pirani interlocks which protects the Bayard-Alpert system from premature filament burnout and excess contamination from high pressure operation.

Combining these two technologies Pirani and bayard-Alpert) reduces the complexity of installation, setup, integration and cost.

This Gauge has a D Sub 15 pin Connector and can work with virtually any vacuum pump or vacuum pump system with the proper signal cable. The gauge is intended for operation with an Inficon VCG401, 402, 403 vacuum gauge
