Product information

The water temperature in aquariums is of crucial importance for animals and plants and should therefore be monitored. Most tropical ornamental fish are most comfortable at temperatures between 24 and 26 ° C. But there are also fish which prefer lower temperatures. The discus is one of the fish that is happier in higher temperatures between 27 and 29 ° C.
With the help of heater thermostats (JBL ProTemp S) the water temperature can be increased and with coolers (JBL Cooler) it can be lowered.

Why won’t my thermometer stick to the glass?

Make sure to clean the pane thoroughly before installing the thermometer. Dirt, biofilms and limescale can prevent it from holding. If the thermometer still does not hold, there may be a problem with the Velcro fastener itself. In this case replace both sets of JBL DigiScan Alarm Velcro Pad (Velcro fastener). You will find these under the tab "Spare parts".

Ich kann es nur immer wieder sagen das sie echt Top sind

Jetzt habe ich sie an all meine Aquarien dran will keine anders mehr sehen

T. BOURGAIT - French

Bonne lecture des températures, mais sincèrement qui a programmé les alarmes (non réglables) ? J'ai fait confiance à cette marque sérieuse qui par ailleurs met des DISCUS en photo sur ce thermomètre ! Mais l'alarme à 18°C Minimum ne sert absolument à rien car tous mes Discus seront morts à une température aussi basse. Et celle maximum de 28°C est aussi ridicule quant on connait les Discus qui demandent des soint par choc Thermique à 34°C. Franchement je ne recommande pas ce produit pour un aquarium à Discus (surtout comme dans mon cas pour surveiller la température d'un Bac de quarantaine). JBL devrait apporter plus d'attention à son support Marketing (photos de Discus) et au réglage technique de ses produits. Par ailleus il n'est pas bien expliqué que ce produit n'est pas reprogrammable !!! 2 étoiles juste pour la bonne valeur de la température !

bennys riff welt - German

ich bin auch sehr begeistert es ist sehr genau und schon ist das man nichts mehr im Aquarium hat. Ich kann es sehr empfehlen

aquarium.meer91 - German

Ein super Thermometer was zuverlässig und genau misst.

Ich finde es sehr toll das es nicht im Aquarium ist sondern von außen angebracht wird. Dank der Kletthalter ist ein einfaches Batteriewechseln möglich.

T. Fischer - German

Ultra genaue Anzeige! Habe extra ein Präzisionsthermometer als Kontrolle im Becken! Warnt bei zu niedriger oder zu hoher Temperatur! Das Thermometer überzeugt auf ganzer Linie!

samija_aquaristik - German

Sehr leichte Anbringung, bei mir auch sehr genau (Gegenmessung im Becken erfolgt). Sollte sich die Temperatur in bedenkliche Bereiche verändern, wird der Alarm hier sicher auffallen, gute Idee!

_aqua4you_ - German

Die Montage war kinderleicht. Es ist zu empfehlen die Scheibe vorher mit dem JBL Clean Aqua zu reinigen. Damit haben die Klebepads eine bessere Haftung. Alarm blinkt auf bei unter oder überschreiten der Solltemperatur

Aquarianer_Lehrling - German

Toller Helfer für den Sommer, schaut auch noch klasse aus . Mit Klett um in mal abzunehmen. 👍🏻
