3/4″ Pyrex, Iridium Filament
Our Bayard Alpert, G75P ionization gauge is a 3/4" glass tubulation, single coated iridium filament gauge. Our iridium filament gauge is your best choice in an oxygen rich environment and can even tolerate brief exposure to atmosphere when hot. Our gauges are most accurate continuous indicators for pressures below 1 x 10-3 Torr. See our Ionization Gauge Operating Details and Ionization Gauge Cross Reference Guide.
