Product Features

Safe, Non-Toxic PET Liquid Crystal Material
Made from high-quality PET with embedded liquid crystal technology, this strip is completely free from harmful chemicals. It is safe for use around fish, reptiles, amphibians, plants, and other pets because it contains no mercury, glass, or liquid components. The material is durable, flexible, and designed to withstand long-term use.

Temperature Range: 18°C to 34°C
Ideal for most aquatic and terrarium environments, this range covers common temperatures for cold-water, tropical, and marine aquariums. It also suits fermentation, plant propagation, and general household temperature checks.

Accuracy Within ±3°C
Offers reliable, easy-to-read temperature indication suitable for everyday use. While it is not a precision scientific instrument, it provides trustworthy readings for general monitoring, helping you maintain a stable environment for your pets or projects.

Simple Installation with Peel-and-Stick Adhesive
No tools or setup required. Just peel off the protective films and press the strip onto any clean, dry, smooth surface such as aquarium glass or plastic containers. The adhesive is strong enough for long-term use and keeps the display securely in place.

The lightweight construction ensures it adheres easily without adding pressure to the tank walls. Perfect for glass tanks of any thickness or small desktop aquariums.

No Mercury, No Battery, No Charging, No Liquid, No Suction Cups Required
The thermometer operates entirely through liquid crystal temperature reaction, meaning no power source, no replacement parts, and no risk of leaking or poisoning. Its simple design makes it a long-lasting, low-maintenance solution.

Important Notes

• The adhesive is designed for single use and cannot be reattached once removed.
• The thermometer is for external application only; do not place it inside the tank or underwater.
• Avoid direct or prolonged sunlight on the strip, as it may distort temperature readings.
• Not intended for use in environments above 50°C (122°F).
• This strip offers general indication; for highly precise measurements, a digital immersion thermometer is recommended.
• The display is not illuminated, so temperature visibility may vary depending on surrounding lighting conditions.
• Temperature display shown in product images may appear enhanced for demonstration clarity.
• Temperatures lower than 18°C or higher than 34°C will not register on this strip.


Quick Function Test

To confirm operation, press the thermometer against a warmer surface such as your palm. The strip should show a reading if the temperature falls within its supported range. This ensures the liquid crystals are active and functioning correctly.
