ThermoWorks / ThermoDrop Black

■ A One-of-a-Kind Digital Thermometer
For example, if you want to know the minimum temperature at night or the maximum temperature during the day while camping in a tent.
With a range of -25 to 50°C and a function to record the highest and lowest temperatures, the Thermo Drop allows you to easily check this with a single button.

Weighing only 14g, it's incredibly lightweight, has a cute design, and can be attached anywhere. It's also dustproof and waterproof (IP67), so you can use it on your mountain trips with peace of mind.
The easy-to-read large dial without unnecessary displays also features an auto-reverse function, and the backlight ensures excellent visibility even in a dark tent.
As it's an overseas product, the temperature is displayed in °F, but it can be easily switched to °C.
The battery life is approximately 4000 hours (about 167 days), and it uses a CR2025 lithium coin battery, which is readily available anywhere in Japan (even at convenience stores), making it a convenient choice.
