自动稀释式 BOD 分析仪
Manual dilution is where most BOD5 errors start. This analyzer prepares programmable dilutions from 1:5 to 1:500, doses seed automatically and fills up to 20 bottles per batch within ±1 percent volume accuracy. Oxygen is read by optical or membrane sensor, and incubation runs at 20 °C in a separate cabinet. Ideal for labs reporting to regulators.
