Application

Tips: How does this sensor compare to traditional membrane-based dissolved oxygen sensors?

Unlike traditional sensors, this fluorescence-based sensor does not require electrolyte solutions or frequent membrane replacement, significantly reducing maintenance efforts and costs. It also has a longer lifespan and is unaffected by water flow or fouling, making it more reliable in long-term monitoring applications. The fluorescence method also provides faster response times and higher accuracy, especially in low-oxygen environments.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
