Applications

Tips: How accurate are air quality monitor sensors?

Different models of air quality monitor sensors vary in accuracy, usually domestic air quality sensors are suitable for daily monitoring of environmental quality, while industrial air quality sensors are more accurate and suitable for specialised situations such as laboratories or environmental testing stations. When in use, you should calibrate the device regularly and follow the maintenance advice provided by the manufacturer to ensure the accuracy of the test results. And, air quality monitoring sensors require regular maintenance to ensure accuracy. Maintenance typically includes cleaning the sensor surface, replacing or cleaning the filter, and calibrating the device for a specific period of time.

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.
