Product information

Healthy fish and plants
Fish depend on a suitable surrounding temperature because, as cold-blooded animals, they cannot regulate their body temperature themselves. Cold-blooded animals’ vital functions decrease as the temperatures fall. The right aquarium temperature is vital if they are to maintain their food intake safely and keep their metabolic processes functioning smoothly.
The fish’s ideal surrounding temperature varies according to their origin. The JBL glass thermometer helps you to keep an eye on the temperature.

Precision measuring
The ideal temperature range is marked on the glass thermometer. A suction cup makes it easy to attach inside the aquarium. It floats vertically if not attached.

Gut ablesbar. Der Saugnapf hält das Thermometer an Ort und Stelle.

Ein günstiges Thermometer für den schmalen Geldbeutel das jedoch gut die Temperatur abmisst!

Hallo!

Ich durfte vor kurzem einige Thermometer von JBL testen. Das Aquarium Thermometer Float ist ein sehr genaues Thermometer. Es ist schnell einsatzbereit und braucht lediglich mit dem Saugnapf von Innen an die Aquarienscheibe gedrückt werden. Ich benutze diese Art von Thermometer in meinen Aufzuchtbecken und bin sehr zufrieden. Sollte ein Saugnapf jedoch einmal nicht mehr halten kann man auch hier Ersatzsaugnäpfe kaufen.

Das JBL Aquarium Thermometer Float kann ich daher auch wärmstens weiterempfehlen da es gut und genau misst und auch für den schmalen Geldbeutel geeignet ist. Gerade wenn man mehrere Becken ausstatten muss kann es ja schon schnell ins Geld gehen ;-)

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.
