BOD analysis system oxiTop IS12
OxiTop IS12 analysis system The main part of the OxiTop measuring system for determining BOD (biological oxygen demand) is the pressure sensor. A sample of the water being tested is placed in a BOD bottle and closed with a lid with a built-in sensor. The flask is installed on an automatic magnetic stirrer with a programmed stirring cycle, included in the delivery set, and placed in a thermostat. At certain intervals, readings recalculated to the level of biological oxygen consumption are entered into the sensor’s memory and taken by the user only on the last day of measurements. -IS sensors have a memory of 5 measurement units, an LED display and a measurement range of 40 units (1 unit = 3.55 hPa). Sensors -C have a memory of 360 values and a measurement range from 500 to 1350 hPa. Programming, collection and processing of data is carried out using the OS 100 remote control, capable of controlling up to hundreds of BOD bottles simultaneously. There are two versions of systems: for 6 and for 12 bottles. · Portability · Accuracy and reproducibility of readings · No mercury-containing sensors · Digital display (-IS) or remote control for data processing (-Control) · Measurements are carried out in accordance with the standard method DIN 38409 part 52 · Wide measuring range with over-range indication · AutoTemp function - an advanced method of temperature control ensures automatic start of measurements at the optimal temperature · Perfect mixing circuit - does not require any maintenance · Automatic zero setting at start measurements · built-in memory for storing the results of 5-day measurements and, as a result, no need for daily measurements · the ability to conduct analyzes on weekends (automatic data storage) · powered by batteries with a service life of 2 years.
