Essential Info

The Extech Instruments 407760 USB Sound Level Datalogger measures and stores approximately 130,000 readings. Using the supplied WindowsTM software, the datalogger can be configured for datalogging rate, high/low alarm limits, frequency weighting, response time, start-mode, and other parameters. The software is also used to download the stored data to a PC. Sound Level data can then be graphed, printed and exported to other applications. The data logger is supplied with a long-life lithium battery, which can typically allow logging for one year. With careful use, this meter will provide years of reliable service.
