RHOSONICS 9585 COD分析仪

COD measurement for breweries

This model is mostly used as a COD (Chemical Oxygen Demand) meter for waste water treatment in breweries. For a COD application, a calibration matrix is used to measure the concentration with a high degree of accuracy. You can have a look at the application for further details. Model 9585 determines the COD concentration with an ultrasonic probe that includes a PT100 temperature sensor and an electrodeless conductivity probe. Unlike Model 9570 and Model 9580, this 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 launder or spool piece.
