Portable Trace Oxygen Analyzer (0 - 1000ppm) with USB Data Logging - EQ-W2000-LD

In stock
Item Number: EQ-W2000-LD
The W2000 is a microprocessor based portable trace oxygen analyzer designed for continuous or intermittent monitoring of oxygen concentration in various gas environments. It comes with a full-color backlight display for visibility and ease of use. Oxygen content data is relayed in real time by a precision electrochemical sensor with compensation for temperature variations. Its portable design makes it ideal for monitoring oxygen concentration in annealing, heat treating, and inert gas welding applications.

Warning: Sensor should ONLY be used with flowing inert gas. Never use it under vacuum conditions, the sensor would suffer damage otherwise.



  • Precision electrochemical sensor provides precision reading with rapid response time
  • Large color display with user friendly menu for ease of visibility and use
  • Five Standard Analysis Ranges: 0 to 10ppm/ 100ppm/ 1000 ppm/ 1%/ 25% with Auto-Ranging or Manual Range Mode
  • Onboard data logging function via removable USB Drive
  • Portable design with rugged polypropylene enclosure for use in hard to access areas
  • Built in rechargeable battery provides portability; universal 100 - 240V AC Adapter is also included for continuous use while plugged in
  • Comes with 1/4" Swagelok fittings for easy connection to gas lines (NOTE: flow rate should be between 0.5 - 5 SCFH, and inlet pressure should be between 5 - 50 PSIG) 

  • Measuring Ranges                         5 Modes: 0 - 10ppm, 0 - 100ppm, 0 - 1000ppm, 0 - 1%, and 0 - 25%
  • Display                                           Large color screen with backlight
  • Response Time (T90)                    10 seconds
  • Calibration                                      Periodically
  • Temperature Compensation           Integral
  • Power                                             Rechargeable Battery & 100 ~ 240V AC Adapter                                                       
  • Enclosure                                       Rugged polypropylene construction with carry handle

Oxygen Sensor


( Spare sensors can be purchased for $199 each )

Two Sensor Types Available (Please click "EQ-W1000-Sensor-LD" to purchase the needed sensor - NOT INCLUDED):
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 system is NOT included)
  • Micro fuel cell technology
  • Accuracy:                                        +/- 1% Full Scale Range
  • Repeatability:                                  +/- 0.5% Full Scale

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.
  • 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.
