9585: COD Meter
COD measurement for breweries
The COD Meter Model 9585 is an instrument which is used for COD (Chemical Oxygen Demand) measurement in the influent flow of wastewater treatment plants in the beer industry. For this COD application, a calibration matrix is used to measure the concentration with a high degree of accuracy.
Model 9585 determines the COD concentration with an ultrasonic probe that includes a PT100 temperature sensor and an electrodeless conductivity probe. The analyser also measures the attenuation and acoustic impedance. The ultrasonic probe is made of 316L or Hastelloy and PEEK, and is normally mounted in a pipe line, reservoir or launder by means of a fixed UTP tank probe or by a spool piece.

8500: Concentration analysers
The model 8500 series is an ultrasonic concentration analyser that enables the accurate measurement of concentrations of chemicals. These analysers can be fruitfully applied to measure electrolyte solutions, liquid purity, and hydrocarbon concentrations in water. The model 8500 series allows measurement of nearly 100% of all single chemical solutions in water. It is the most reliable and most powerful instrument to measure the composition of industrial liquids. Thanks to its innovative electronics and sensor design, it allows for continuous in-line monitoring of diluted solutions with a very high degree of accuracy. Furthermore, these analysers lack moving or degrading parts, which means that virtually no maintenance is needed.
