Dissolved Oxygen measurements are essential to water quality, Biology, Earth Science and Chemistry investigations. Wide range (0 to 20 mg/L) ensures the sensor does not top out before the experiment is over. * Excellent resolution (0.01 mg/L) allows students to see small changes. * Temperature compensated -- essential for consistent measurements. Typical Applications: * Measure oxygen consumption by yeast during respiration * Investigate how the presence of organic matter affects DO levels * Study biological oxygen demand (B.O.D.)
