How accurate is this temperature humidity sensor?

This thermometer hygrometer offers high precision. Readings update every 10 seconds, so you always know the real-time conditions—whether for your family's health, your greenhouse, or your cherished jars and collections.

Does it come with batteries installed? How do I replace them?

Yes, this digital indoor thermometer comes with an LR44 battery already installed and ready to use. The battery cover slides open horizontally—just slide it to replace when needed. No tools required.

How can I place or mount this thermometer?

•Stand it—the square design sits firmly on any flat surface •Dhesive Mounting — Use the included double-sided tape to attach to a smooth, dry surface. •Embed it—fits into a precision-cut opening (1.81 × 1.06 inches) for a clean, built-in look

Can I use it outdoors or in a reptile tank?

Yes, this portable thermo-hygrometer is great for indoor and outdoor use—reptile tanks, greenhouses, cars, and more. Just avoid direct sun, rain or extreme temperatures outside its rated range (-58°F to 230°F).

Why does the reading seem off when I first use it?

That's normal. When first unpacked, allow 15–30 minutes for the sensor to acclimate to the room before it reaches full accuracy. Also, readings may fluctuate slightly during the first few minutes after inserting new batteries—this is expected.
