After sticking it to the aquarium glass, the JBL Aquarium Thermometer Digital needs a few minutes to acclimatise. The same applies with strong temperature changes. All the fields are black at first. The ambient temperature determines the colouring of the scale marks. The topmost clear colouring, let’s say it’s green/blue, is the current temperature. The areas above remain black, the scale points that have already been exceeded turn black again.
