UHV-24p Bayard-Alpert Gauge Tube (CAT#: AM-LE-0485-Y)

The UHV-24p Bayard-Alpert Gauge Tube is manufactured by Agilent Technologies. It uses a heated filament as an electron source and can work in a wide operating pressure range, measuring pressures below 2 x 10 -10 torr.

Pressure range:
5 x 10^-12 to 1 x 10^-3 Torr
6.7 x 10^-12 to 1 x 10^-3 mbar
Sensitivity: 20 Torr^-1
X-ray limit value: 5 x 10^-12 Torr (6.7 x 10^-12)
Measurement accuracy: within the pressure range does not exceed 20% of the full range
Transmitting current: default 4 mA (10 A to 9.99 mA)
Baking temperature: 450 °C, with cable connection
Temperature limit: operating temperature 0 °C to 250 °C; storage temperature –15 °C to 80 °C
Degassing: electron bombardment 400 V at 65 mA
Material: 304 stainless steel, ceramic, kovar, iridium or tungsten

• Provide long-life thorium-coated iridium or tungsten wire
• Easy filament replacement
• Suitable for high vacuum applications
