Sensor Types
Glove Box Sensor
Provides the best response when used in enclosed environments where battery R&D is conducted; measures trace oxygen levels in purge gases (e.g. N2 and Argon).
                       (Image for reference only, Glove Box system is NOT included)
Furnace Sensor
Designed for CVD applications when acid and aggressive gases (e.g. CO2, HCI, HCN, and etc.) will be present.
                         (Image for reference only, Furnace system is NOT included)
Weight 1 lbs
Notes & Warnings
  • The analyzer is designed for measuring trace oxygen in the presence of gas flow; it may not measure reliably when gas is static.
  • NEVER use the oxygen sensor under vacuum conditions. The vacuum will cause irreversible damage to the sensor.
  • ONLY USE the furnace oxygen sensor with CVD furnace systems to prevent contamination and damage to the sensor.
    • To prevent sensor damage, please use quick ON/OFF valves ( two included per order ) to isolate the sensor from open-air and maintain it with an inert gas at all times. Click the picture below to learn more about this setup:
  • Due to the variations in electronics and sensor technology, minor deviations in O2 reading performance may be experienced when using O2 analyzers or sensors from a different brand, technology, and etc.
  • The oxygen sensor is consumable and not covered by warranty, damage caused by misuse is also excluded from coverage.
