USB recorder for temperature and humidity. Memory: 32K readings: Measures and stores up to 16,382 humidity readings and 16,382 temperature readings,, range from -35°C to 80°C (-31°F to 176°F) and 0 ~ 100% RH, configurable sampling intervals from 10s ~ 12hrs, USB 1.1 and 2.0 compatibility, battery and software included.

The USB-502 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) range. The user can easily set up the logging rate and start-time, download the stored data by plugging the module straight into a PC's USB port, and run the purpose-designed software under Windows 2000/XP/Vista. Relative humidity, temperature, and dew point (the temperature at which water vapor in the air begins to condense) data can then be graphed, printed and exported to Excel. The data logger is supplied complete with a long-life lithium battery, which will last for up to a full year. Logger status is indicated by two flashing green/red LEDs. The data logger is protected against dust/moisture ingress to IP67 when the protective cap is fitted.
