Dissolved-Oxygen BOD Measurement System

溶解氧法 BOD 测定系统

Referee labs and method-validation work still rely on the classic route: dilute, measure oxygen, incubate, measure again. This system uses standard 300 mL bottles, a 20 °C incubator and a membrane or luminescent probe resolving 0.01 mg/L. Five-day tests are standard, with 7 or 10 days optional. It also makes a solid training setup.

It also makes a solid training setup.

Highlights

  • Follows the reference dilution approach for referee BOD5 results
  • Choice of membrane or luminescent optical oxygen sensor
  • 0.01 mg/L resolution and ±0.2 mg/L oxygen accuracy
  • 5-day standard tests, with 7- or 10-day options

Applications

  • Regulatory BOD5 determinations
  • Referee analysis and method validation
  • Municipal and industrial effluent testing
  • Laboratory training in BOD methodology
