BOD AL606 Measurement System
The AQUALYTIC® sensor system BOD AL606 allows precise measurement of BD based on the manometric principle. Manometric respirometers relate wxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurement. The measured values are read out comfortably via the front panel. There are no batteries required in the sensor heads. Advantages - Accurate and direct display of BOD values in mg/l
- User-friendly handling
- User-selectable measuring period from 1 to 28 days (BOD 5, BOD 7, OECD …)
- Measuring ranges from 0 – 40 mg/l to 0 – 4000 mg/l BOD, sample volume related
- Automatic start function following temperature equalisation of the samples
- Mercury-free, environmentally friendly BOD determination
- Inductive stirring system with automatic re-centering of stirring rods
- Direct sample selection
- Interface RS 232
Inductive stirring system
The microprocessor-controlled AQUALYTIC® inductive stirring system is non-wearing an maintenance-free. At regular intervals, the magnetic stirring rods are accelerated and slowed down again, taking them up to maximum speed and back down again. This ensures the centralization of the stirring rods. Stirring rods that move away from the center of the bottle are re-centered quickly and reliably.
