Waterproof temperature recorder 120 meters Water Temp Pro V2 U22-001

The data recorder U22-001 de temperature of the'water is sustainable and has a resolution 12 bits for measure temperature under different conditions, particularly in air and in water.
It has a precision sensor which provides an accuracy of ±0.2°C, and can measure temperatures ranging from -40°C to 70°C (-40°F to 158°F) in air, and up to 50°C (122°F) in water.
This device is designed for extended use aquatic environments, whether in freshwater or salt water, thanks to its waterproof housing and profiled that can withstand immersion up to 120 metres (400 feet).
In addition, it is equipped with a uSB optical interface which allows the data to be downloaded quickly, even when the recorder is wet or underwater, which facilitates the recovery measures.
In order to obtain accurate measurements of the temperature of the air in the open sun, a solar anti-radiation screen is required (either the RS1 solar anti-radiation screen required for assembly or the M-RSA solar anti-radiation screen pre-assembled).
THE'data recorder U22-001 is a tool affordable for the collection of high quality temperature data, suitable for aquatic environments, and compatible with software HOBOware Pro for configuration, graphical visualisation and analysis of recorded data.

Technical specifications:

- Quality research measures at an affordable price
- Waterproof up to 120 meters (400 feet)
- Reading data in less than 30 seconds via fast optical USB interface
- Compatible with HOBOware Pro software for configuration, graphics and analysis of the recorder

Recorder functionality:

- Operating range † 40° to 70°C (-40° to 158°F) in air, maximum sustained temperature of 50°C (122°F) in water

† Important: The plastic housing will become brittle at temperatures below -20°C.
If the recorder is deployed to a location where the temperature drops below -20°C, make sure that the recorder remains motionless and is not pulled or struck. Return the recorder to a temperature above -20 °C before handling it.
