Ion Gauges

Overview
SRS offers three types of gauges for the IGC100 Ion Gauge Controller: glass-tubulated, nude, and nude-UHV Bayard-Alpert ionization gauges. We also supply convection-enhanced Pirani gauges. All single, hair-pin shaped filaments used in SRS gauges are spring tensioned to eliminate filament sag. This allows the user to mount the gauge in any orientation. Dual-filament assemblies provide security against filament burnout.

SRS Ion Gauges

  2. Select filament type: ThO2/Ir or tungsten, single or dual
  3. Note the SRS part number, and click on one of the Quick Links (Prices, Buy Online, Get a Quote) above
