Tips: Application of digital conductivity meter

Conductivity measurement of RO membrane equipment: Digital conductivity meter is suitable for monitoring the conductivity of liquids such as pure water and raw water during the processing of various RO (Reverse Osmosis) membrane equipments.
Conductivity measurement of water and fertilizer: Online conductivity meter can measure the conductivity value of the solution and feed back the signal to the PLC to achieve the precise ratio of water and fertilizer and effectively reduce waste.
Process measurement of conductivity: Monitor the change of liquid conductivity during ultrasonic cleaning, circulating water in air conditioning, and electroplating production, and can set upper and lower limits to achieve automatically alarm.
Environmental water quality monitoring: It is suitable for on-line monitoring of liquid conductivity of tap water, seawater and sewage exhaust outlets, and data can be transmitted with MODBUS via RS485.

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.
