Hot Ionization Gauges


Bayard-Alpert Pirani Gauge BPG400

  • Extremely wide measurement range from 5×10-10 mbar to atmosphere (3.8×10-10 Torr to atmosphere)
  • Excellent repeatability in the process pressure range from 10-8 … 10-2 mbar of 5%
  • The Pirani interlock protects the Bayard-Alpert system from premature filament burnout and excess contamination from high pressure operation
  • Long-life yttrium oxide coated iridium filament
  • Optional graphic display and Fieldbus interfaces available
  • Automatic high vacuum Pirani adjustment reduces operator interventions
  • RoHS compliance
  • General vacuum measurement and control in the low to ultra high vacuum range
