Battery-Powered Temperature/Humidity Logger Is USB Based

A battery-powered temperature/humidity logger, the USB-502-PLUS, is a cost effective solution for both long- and short-term logging applications in which accuracy and small size are important. The standalone USB-based logger measures and stores up to 16,382 relative humidity and 16,382 temperature readings over the 0 to 100% relative humidity range and ?35°C to 80°C range. It also calculates dew point. Overall temperature accuracy is ±0.3°C typical, ±1.5°C maximum. Overall relative humidity accuracy is ±2.0 typical ±4.0 maximum. Sampling rates of 10 s to 12 hr. are available. Flashing LEDs indicate logging status. A user-replaceable long-life lithium battery, which is included, typically allows up to one year of data logging. The USB-502-PLUS comes with the USB-500 Series Data Logging Application software. The 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. Users can display time-stamped temperature, relative humidity, dew point, and alarm limits on a strip chart graph. The data can also be downloaded to a text or a .csv (comma separated values) file. The data logger and software are compatible with Windows 2000/XP/Vista. The USB-502-PLUS costs $110 and is available now. MEASUREMENT COMPUTING CORP., Norton, MA. (508) 946-5100.
