This datalogger measures and stores up to 10,000 readings.

The user can easily configure the logging rate, high/low alarm and start-mode. It also downloads the stored data by plugging the 

module into a PC USB port and running the supplied PC software. Data can then be graphed, printed and exported to other applications. The data logger is supplied with a 3.6V ½ ‘AA’ lithium battery.
