HOBO Pro Dataloggers

The new HOBO Pro loggers feature a 100% weatherproof case, 64K of memory, high resolution mode, and improved accuracy, making them ideal for a variety of natural resource applications. The archive feature automatically stores data from the last seven deployments and all data is stored in nonvolatile EEPROM memory so it is safe even if the battery fails. With the easy to use BoxCar Pro Software (order separately), you can choose a sampling interval or specify a custom interval, select a starting date and time, choose the resolution, and download recorded data. Data can also be retrieved with the HOBO Shuttle (sold separately), allowing the logger to be downloaded and relaunched while remaining in the field. Files are easily exported to spreadsheet programs or they can be graphed and printed directly from BoxCar Pro.

Each logger comes with user replaceable 3 year lithium battery, mounting tabs, self tapping screws, and hook and loop tape for mounting. The dual channel temperature logger comes with a temperature sensor with 6' lead.
