Only 3×4 cm, this tiny data logger measures temperatures over a wide temperature range.

• Waterproof to 300 m (1000')
• Data readout in less than 30 seconds via fast Optic USB interface

The TidbiT v2 Temp logger is Onset’s smallest U-Series logger. Its durable, waterproof case is designed for extended deployments measuring temperature in streams, lakes, oceans, coastal habitats, and soils. The logger’s small size allows it to be easily mounted and/or hidden in the field. It is waterproof up to 305 m (1000 feet) and rugged enough to withstand years of use. It has enough memory to record over 42,000 12-bit temperature measurements.

The logger uses an optical USB communications interface (via a compatible shuttle or base station) for launching and reading out the logger. The optical interface allows the logger to be offloaded without compromising the electronics. The USB compatibility allows for easy setup and fast downloads.
