- Challenge OLR Respirometer | Features Up Level  
  Features Applications Specifications Support
Features of the Challenge OLR Respirometer include:
  • The reaction chamber allows you to simultaneously feed aeration tank mixed liquor and your wastewater sample
  • The high-speed mixing lets you measure oxygen uptake rates in excess of 150 mg/l/hr
  • The built-in computer gives you instant monitoring of your data
  • Oxygen uptake rate measurement is relatively independent of temperature variations
  • Oxygen uptake rate measurement is also relatively independent of barometric pressure variation
  • With the OLR you won't have to calculate mass transfer coefficients (KLa)
  • You can use a high fill rate (fill the reaction vessel in 2 to 4 minutes) for batch tests
  • You will accomplish a high turnover of mixed liquor in the continuous mode(hydraulic retention times of 15 minutes to 12 hours)
  • WindowsTM-based programs are used for system control and data acquisition
