The Measurement Computing USB-502-LCD data logger measures and stores up to 16,379 relative humidity and 16,379 temperature readings over a 0 to 100 percent RH range and a -35 to +80 °C (-31 to +176 °F) temperature range. You can easily set up the logging rate and start time and download the stored data by plugging the module directly into a PC’s USB port and running the purpose-designed software under Windows Vista/XP/2000. You can then graph, print, and export relative humidity, temperature, and dew point (the temperature at which water vapor in the air begins to condense) data to Excel. The high-contrast LCD can show a variety of temperature and humidity information. At the touch of a button, you can cycle between the current temperature and humidity, along with the maximum and minimum stored values for temperature and humidity. The data logger features a long-life lithium battery, which can typically power logging for up to one year.
