This sound datalogger is designed to work in tandem with Extech's free software (included as standard). By using the software, you can configure the 407760 to log sound levels at different intervals (50ms, 500ms, 1 second, 2 seconds, 5 seconds, 10 seconds or every minute) and configure different parameters such as start time and frequency rate.

Once you're done configuring, simply place the logger where you want to measure, activate, then leave for a period of time. When you're done logging, plug it back into PC, download the data into the software and then you can view back results, export into different programs and even create custom graphs based on your measurements.

Up to 129, 260 individual sound measurements can be directly stored on the Extech 407760's internal memory, making this product ideal for prolonged surveys.
