RHOSONICS 9590 多组分溶液分析仪

Concentration meter for dual chemicals: intrusive system

This model is ideal for applications where two chemicals need to be measured, such as H2S04 & Cu++ and HCl & FeCl2. These liquids are commonly used in electroplating and pickling applications. Two concentrations are determined by measuring the velocity of soundy, temperature, and conductivity. Model 9590 and model 9595 measure the sound velocity and ultrasonic density with an ultrasonic probe; no other sensors are required, which is a large advantage. The ultrasonic probe is made from Hastelloy and PEEK, and is mounted in a PVDF or PVC cell (which makes it a bypass). Other mounting options are possible on request.

For less abrasive media, such TMAH+PR, we recommend the use of our model 9570. PEEK is a very abrasive and corrosion resistant material, which makes this model a high quality sensor that can be used in very harsh media. The difference between Model 9590 andModel 9595 are the options for installation: Model 9595 can be used for wafers in pipelines.
