  • What range does the hydrometer scale cover?

    With a reading accuracy of 0.0005 units, the hydrometer is extremely precise. The built-in thermometer, which displays temperatures from 9°C to 32°C, and the temperature correction scale ensure maximum accuracy. The density is determined within a range of 1016 and 1028

    War diese Antwort hilfreich?
  • The hydrometer is broken. It contains a red liquid. What is this liquid made of, and is it toxic?

    The hydrometer does not contain mercury. The liquid is an alcoholic solution with dye. The liquid is not toxic. Both ingredients are quickly broken down by bacteria in the aquarium. The dilution effect should also be noted. The silver beads are made of an iron compound and are therefore harmless. They should simply be sucked out.

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.
