Measurement Computing's USB-502-PLUS 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) temperature ranges.
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®. 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. It also features software configurable data rollover allowing unlimited logging periods by overwriting the oldest data when the memory is full.
"We had expected to spend hundreds, if not thousands, of pounds on sensors and data recorders and then a complex task of installing instruments and getting them to talk to each other. Instead, a simple device containing the sensors that both records and logs temperature and humidity was ordered and arrived within days." John Fleming, Helensburg Music Society
