This meter has a built-in USB port which connects to a laptop PC for recording the sound level over a period of time. This is an ideal instrument for noise monitoring in factory, school, business and traffic areas. This meter conforms to the IEC61672-1 Class 2 and ANSI S1.4 Type 2 standards.

With its internal memory, this unit can record sound level over a period of time without connecting to a computer. This device operates on a 9V battery (about 30 hours) or an AC adapter (included). It is very accurate (+/- 1.4 dB) and durable, an ideal companion for your field projects. A heavy duty carrying case is also included for the protection of the device.
