Features

  • Zirconium oxide O2 sensor housed in 700°C furnace for exceptional accuracy and reliability
  • Ex-situ convection loop design for simple installation and fast, easy maintenance
  • Suitable for temperatures to 1900°C
  • Intuitive microprocessor-based controller with configurable display for field programming
  • Auto-calibration and auto-verification
  • Auto Blow-back feature for use in extremely harsh environments
  • Optional platinum-catalyst combustibles sensor measures CO & H2 for detecting incomplete combustion

Applications

The OxyTrak 390 flue gas analyzer measures unburned oxygen levels in dirty, aggresive combustion applications including:

  • Boilers - all fuels and all types, including marine, recovery and utility
  • Furnaces - all fuels and all types, including heat treating, glass and process
  • Rotary kilns - ore reduction, cement, alumina processing and others
  • Incinerators - industrial, municipal and hazardous waste

Specifications

The OxyTrak™ 390 combines state-of-the-art measurement technology with a unique sampling design. The result is an accurate low-cost analyzer that stays on the job for extended periods with minimal maintenance. It responds in seconds to changes in flue gas concentrations of oxygen and/or combustibles, continuously providing the information you need to keep your boiler or furnace operating at maximum efficiency.
