Stick-On Thermometer Strips — Dual Scale, 5 Pack

Thin liquid-crystal strips that stick to the outside of the glass and read the tank temperature in about a minute. Dual scale (°C and °F), no batteries, nothing in the water — one on every tank you own.

• Instant read. Colour band shows the current temperature at a glance, 18-34 °C range.
• Dual scale. Both Celsius and Fahrenheit on every strip.
• Zero intrusion. Nothing inside the tank to trap debris or interest a curious fish.
• Five strips per pack. One per tank, or spares for when one peels after a rescape.
