Portable Trace Oxygen Analyzer (0 – 1000ppm) with USB Data Logging

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.

• The 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 0.5 – 5 SCFH (w/ Glove Box sensor) or 0.5 – 2 SCFH (w/ Furnace Sensor), and inlet pressure should be between 0 – 50 PSIG) 
• Measuring Ranges                         5 Modes: 0 – 10ppm, 0 – 100ppm, 0 – 1000ppm, 0 – 1%, and 0 – 25%
  
• Display                                           Large color screen with backlight
