The Onset Hobo TidbiT v2 water temperature datalogger delivers 12-bit resolution and has ±0.2 °C accuracy and measures temperature over a vast temperature range. An optical USB interface permits users to offload data in a matter of seconds. The data logger is only 3x4 cm making it compact and convenient. Its exclusive design is ideal for both outdoor and underwater environments as it is waterproof to 300m (1000ft). 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).
IMPORTANT: This HOBO data logger requires HOBOware software and a communications device.
