The JBL O2 test set is a means of exactly determining and routinely controlling the oxygen content in fresh water and marine tanks, tap water and ponds within a range of 1 - 10 mg/l (ppm).


  • Recommended oxygen content: 8 mg/at 25° C
  • Test providing accurate readings of oxygen levels from 1 - 10 mg/l in freshwater and marine tanks as well as garden ponds
