Stick-on Thermometer for Home Brewing Buckets & Demijohns

The stick-on LCD thermometer strip provides a simple, power-free way to monitor temperature on any smooth surface. Ideal for home-brewing buckets, fermenters or aquariums, this adhesive strip changes colour to indicate the current temperature—no probes, batteries or wiring required. Just peel, press and read.

Featuring a series of liquid-crystal cells calibrated in both °C and °F, the strip “glows” at the cell matching your vessel’s temperature, giving you an instant visual reading at a glance. Its slim, waterproof design clings securely to plastic, glass or metal and disappears into your setup when not in use.
