TidbiT v2 Water Temperature Data Logger - UTBI-001

The tiny TidbiT v2 has 12-bit resolution and a precision sensor for ±0.2 °C accuracy over a wide temperature range. The rugged TidbiT is waterproof to 300m (1000 ft). Data readout is available in less than 30 seconds via the Optic USB interface. For accurate ambient air temperature measurements in sunlight, a solar radiation shield is required (RS1 Solar Radiation Shield, assembly required; M-RSA pre-assembled Solar Radiation Shield).

Features:

• 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

The CE Marking identifies this product as complying with the relevant directives in the European Union (EU).

* To guarantee accuracy, the TidbiT v2 Temp must not be used in condensing environments and water temperatures higher than 30C (86F) for more than eight cumulative weeks over the life of the logger. Frequent or prolonged exposure will lead to measurement drift and eventual failure.
