This Lascar USB RH / Temperature and dew point data logger comes with a long-life lithium batter
Features & Applications:
This standalone data logger measures and stores up to 16,382 relative humidity and 16,382 temperature readings over 0 to 100%RH and -35 to +80°C (-31 to +176°F) measurement ranges. The user can easily set up the logger and view downloaded data by plugging the module into a PC's USB port and using the supplied software. Relative humidity, temperature and dew point (The temperature at which water vapor present in the air begins to condense) data can then be graphed, printed and exported to other applications. The datalogger is supplied complete with a long-life lithium battery, which can typically allow logging for 1 year.
