The USB-502-PLUS, from Measurement Computing Corporation, is a new battery-powered temperature/humidity logger. It ideal for both long- or short-term logging applications in which accuracy and small size are important. The USB-502-PLUS is a high-performance version of the USB-502. The PLUS version offers three times the temperature measuring accuracy, one and a half times the relative humidity accuracy, and nearly twice the dew point accuracy. USB-502-PLUS is available now for $110.
The USB-502-PLUS standalone data logger 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, and calculates 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.
The USB-502-PLUS logger is supported by USB-500 Series Data Logging Application software, included with the package. This user-friendly, intuitive software is used initially to configure the logger, program alarm thresholds, logging rates, start times, and measurement units, etc. When the logger is retrieved from the field, the software provides simple one-click access to download, display, and export the data. The user can display time-stamped temperature, relative humidity, dew point, and alarm limits on a powerful strip chart graph. The data can also be downloaded to a text or a .csv (comma separated values) file. Supporting these file types allows users to export the logged data easily to Excel spreadsheets and reports with a single mouse click. The software and Measurement Computing USB-500 series data loggers are compatible with Windows 2000/XP/Vista.
