  • Why is there no color chart for GH, KH, Ca, Mg, seawater, and CO2 direct?

    The tests from the test series: JBL GH Test, JBL KH Test, JBL Calcium Test Ca and JBL Magnesium Test Mg are so-called titration tests, in which the number of drops until the color change is counted and the counted value is multiplied by a value: GH = number of drops = total hardness in °dH KH = number of drops = carbonate hardness in °dH CO2 = number of drops * 2 = CO2 in mg/l Magnesium + calcium = number of drops * 120 = total Ca + Mg in mg/l Calcium = number of drops * 20 = total Ca in mg/l Magnesium = total Ca+Mg from magnesium test - total Ca in mg/l = magnesium in mg/l

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

A notification makes it possible to inform the user about an event outside the context of a website, such as a new blog post, a competition or a voucher.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.
