FIELD: biotechnologies.
SUBSTANCE: device comprises a through cell equipped with holes, where at least one hole represents an inlet hole for intake of fluid medium from the specified technological flow, and at least one hole is an outlet hole for discharge of fluid medium from the specified through cell. To one of specified holes an RK probe is attached, possibly, an OVP probe, a cleaning accessory. The first pipeline is connected to the inlet hole. Possibly, the second pipeline is connected to the outlet hole. A valve is connected to the specified through cell. With the help of the specified devices and methods they measure volume microbiological activity and surface microbiological activity in a process flow of water by means of measurement of dissolved oxygen concentration.
EFFECT: method improvement.
