POLYMETRON 9586 Hydrazine Analyzer
The 9586 analyzer can continuously measure the hydrazine content in water. The measurement principle is based on the 3-electrode electrochemical method.
A polarization voltage (480 mV) is applied between the platinum anode (working electrode) and the stainless steel cathode (counter electrode). The oxygen scavenger will be oxidized on the surface of the working electrode, and the current generated is proportional to the concentration of hydrazine, ranging from 0 to 500 ppb.
In alkaline environment, the reaction is more violent, the sample must be adjusted in advance, and then put into the measuring cell to add pH, diethylamine, monoethylamine, ammonia or diisopropylamine to the sample through the venturi tube. To greater than or equal to 10.2. Temperature measurement by sensors integrated in the measuring element
It is suitable for online monitoring of hydrazine in boiler water supply, deoxygenated water and steam in power plants.
-Easy to integrate and easy to operate
According to the complete water quality detection system developed by power plant users. Hach Company can provide a variety of products for users to choose, in order to match these products with each other, forming a flexible solution to meet your unique needs. The comprehensive method adopted by Hach Company can save you time in all aspects of design, installation, training, maintenance and operation.
-Save design time
The same product platform means you spend less time looking for design files or specifications. It also allows you to create and reuse design templates.
-Easy to install
The interchangeable components, the universal operation interface, and the support of the same hash technical team can make the installation faster and easier.
A single platform can reduce the product training time to a minimum, so as to master the use of the new system faster.
-Simplified maintenance and operation
The use of common menu guides reduces the specificity; it provides step-by-step operation guidance for the maintenance and calibration process. When troubleshooting is required, the system will send an intuitive alarm to notify the operator.
