MadgeTech MicroTemp100 Miniature Submersible Temperature Data Logger

The MicroTemp100 is an incredible feat of miniaturization and durability. Despite being only 2.6 inches (66 mm) tall and 0.7 inches (18 mm) in diameter, this tiny data logger packs a powerful punch. It's not just small; it's also designed to withstand high temperatures of up to 100°C (212°F). Additionally, its waterproof design allows it to function underwater at depths of up to 230 feet (70 meters).
