OxiTop IS12 analysis system

The heart of the OxiTop measuring system for determining BOD (biological oxygen demand) is the pressure gauge. A sample of the studied water is placed in a BOD flask and closed with a lid with a built-in sensor. The flask is mounted on an automatic magnetic stirrer with a programmed mixing cycle, which is included in the delivery set, and placed in a thermostat. At certain intervals, readings converted to the level of biological oxygen consumption are entered into the sensor’s memory and removed by the user only on the last day of measurements. The -IS sensors have a memory for 5 units of measurement, an LED display and a measuring range of 40 units (1 unit = 3.55 hPa). The -C sensors have a memory of 360 values ​​and a measuring range from 500 to 1350 hPa. Programming, data collection and processing is carried out using the OS 100 console, which is capable of controlling up to a hundred BOD bottles simultaneously. There are two options for systems: for 6 and 12 bottles.

· mobility
· accuracy and reproducibility of indications
· absence of mercury-containing sensors
· digital display (-IS) or remote control for data processing (-Control)
