Hobo UTBI-001 – Onset
Small TidbiT v2 water temperature data logger, offload data via the BASE-U-4 optic USB base station or the U-DTW-1 waterproof shuttle
This tiny data logger (only 3×4 centimeters) measures temperatures over a wide temperature range. The TidbiT v2 provides 12-bit resolution and has ±0,2 °C accuracy. It is designed for outdoor and underwater environments and is waterproof to 300 meters. An optical USB interface allows users to offload data in seconds. Please note, a solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 Solar Radiation Shield, assembly required: or M-RSA pre-assembled Solar Radiation Shield).
This is Onset’s smallest temperature data logger and is waterproof to 300 meters. You can readout the data in less than 30 seconds via fast Optic USB interface This data logger operates in outdoor and water environments.
The data logger supports the following measurements: soil temperature, temperature and water temperature.
