A flat LCD strip sticks to the outside of the glass and hands you a temperature every time you walk past, with nothing inside the tank to work around at cleaning time.
Key features
The adhesive backing mounts on the outside of a glass or acrylic tank, so it takes up no room inside and cannot be knocked off a rock by a boisterous fish.
Large digits are readable from across the room, which makes it easy to notice a heater problem early.
Several temperature ranges are offered — pick the one that brackets your target from the selector.
Nothing is submerged, so there is nothing to corrode or leach in fresh or salt water.
Be realistic about accuracy, though. A strip is reading the glass rather than the water, so keep it out of direct sun, away from the heater and off the tank's warmest corner, and treat it as a trend indicator rather than a precise figure. When you need a firm number — medicating, acclimatising, chasing a heater fault — confirm it with a glass or stainless thermometer from our Marina range.
