- Onset’s smallest temperature data logger
- Waterproof to 300 meters (1,000 feet)
- Data readout in less than 30 seconds via fast Optic USB interface
Only 3×4 cm, this tiny data logger 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 m (1000 ft). 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).
