Housing & Sensor Combination

The W1000 microprocessor-based analyzer is ideal for the continuous measurement of gas mixtures in applications that demand heavy monitoring of the gas environment. A full-color backlight display shows the oxygen content data relayed by a precision electrochemical sensor in real-time with compensation for temperature and barometric pressure variations. Two fully programmable alarms with built-in delay enable the user to exert more control over processes.
Warning: The sensor should ONLY be used with flowing inert gas. Never use it under vacuum conditions, the sensor would suffer damage otherwise.



  •      •  The precision electrochemical sensor provides precision reading with rapid response time
  •      •  Five auto-ranging measurement scales available: 0 to 10/ 100/ 1000 ppm, 0 to 1/ 25%

Oxygen Sensor


( Spare sensors can be purchased for $199 each )

Two Sensor Types available (
Please select the desired option from Product Options above):

Glove Box Sensor

Provides the best response when used in enclosed environments where battery R&D is conducted; measures trace oxygen levels in purge gasses (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 gasses (e.g. CO2, HCI, HCN, and etc.)
will be present.

(Image for reference only, Furnace is
 NOT included)

Operation Manual


Notes & Warnings

  •      •  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.

    •          º  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.
