U22-001 HOBO Prov2 Data Logger for Water Temperature

Data Logger; the durable HOBO Water Temp Pro v2 has 12-bit resolution and a precision sensor for ±0.2°C accuracy over a wide temperature range. Designed with a durable streamlined case for extended deployment in fresh or salt water, the Water Temp Pro v2 is equipped with an Optic USB interface for data offload in the field, even when the data logger is wet.
For added protection use BOOT Protectors available in Black or White colors.

Features:

• Research-grade measurements at an affordable price
• Waterproof to 120 meters (400 feet)
• Data readout in less than 30 seconds via fast Optic USB interface

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

†IMPORTANT: The plastic case will become brittle at temperatures lower than -20°C. If the logger is deployed in a location where the temperature drops below -20°C, make sure the logger remains stationary and is not pulled on or struck. Return the logger to above -20°C before handling.
