Bulk Specific Gravity

A computer controlled, automated, testing machine, for measuring bulk specific gravity of gyratory samples or field cores of asphalt.

Oxygen Demand Monitor

Easy operation

  • Complete solution for fast, dependable GMB or bulk specific gravity of asphalt cores or gyratory samples
  • Both 150mm and 100mm sizes can be tested
  • Comes with a calibration standard for daily calibration and a computer preloaded with the BSG-200 software
  • The entire process takes less than a minute to complete, and multiple samples can be tested rapidly with no delay between tests
How it works
  • Wastewater can be added to the Reactor Vessel from the influent stream, or mixed liquor can be sampled directly from an aeration basin
  • Oxygen uptake rate data is sent to a 4-20mA output (suitable for SCADA systems), is stored in memory, and can be downloaded via USB memory stick for subsequent processing
  • The data file includes oxygen uptake rate in milligrams/liter/hour and the time and date of data recording
