![]() |
The USB-502-PLUS is a battery-powered temperature and humidity logger, which measures and stores up to 16,382 relative humidity and 16,382 temperature readings over the 0 to 100% RH and -35 to +80 °C (-31 to +176 °F) measurement ranges along with dew point. Flashing LEDs indicate logging status, and a user-replaceable long-life lithium battery is included, which can typically allow up to one full year of logging. It is supported by USB-500 Series Data Logging Application software, which provides one-click access to download, display, and export the data. The data can also be downloaded to a text or a .csv (comma separated values) file, which is compatible with Excel.
