ES B.O.D. Measurement System

B.O.D. MEASUREMENT SYSTEM

Manometric, respirometric BOD measurement system. Specifically designed for
use in laboratories, treatment and purification plants with automatic BOD
measurement at customizable intervals. The unit is a 6 sample system that allows
precise measurements of BOD from 1 to 28 days. Data is stored in the individual
sensor heads, so it is possible to remove and reposition the bottles without losing
vital data. By using different volumes of sample, it is capable of measuring from 0
to 4000mg/l without the need to dilute the sample. Overflow measuring flasks
are supplied with the unit, and a full range of flasks are available. BOD CM
Tablets, which can be used to verify the validity of results, can also be supplied.
The unit is easy to use and set up using scrolling menus on the LCD display.
Results can be monitored throughout the analysis period to ensure accurate
analysis. With a selectable automatic start function, variations in sample
temperature prior to testing can be eliminated, as the unit will begin the analysis
period only when the temperature is constant. Such variations would normally
cause errors during manometric measurement.
The microprocessor controlled inductive stirring unit included provides constant
mixing of the sample over the analysis period.
Supplied complete with 1 x remote control, 6 x sensor heads, 3 x type C alkaline-
manganese batteries, inductive stirring unit with power supply and Y cable, 6 x
sample bottles, 6 x rubber gaskets, 6 x magnetic stirring rods, 1 x 157ml overflow
flask, 1 x 428ml overflow flask, 1 x 50ml bottle potassium hydroxide solution, 1 x
50ml bottle nitrification inhibitor solution and instruction manual.
