FAQ

The phosphate test doesn't show any blue colouration, but instead shows a slightly yellowish colouration, which is not on the colour chart.

This is probably due to an error in use. The JBL Phosphate Test sensitive requires the following reagents:

1) 1 small level measuring spoon (narrow end of the enclosed double spoon) of reagent 1.

2) 10 drops of reagent 2.

3) Shake the sample lightly.

4) Allow 10 minutes for the colour to develop and then read the phosphate level using the comparator block.

It is important to use one small measuring spoon of Reagent 1 and not a large measuring spoon.

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.

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.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
