CEM DT-8852 Industrial High Accuracy Digital Sound Noise Level Meter Data Logger with USB

This is a brand new CEM DT-8852 CE certified digital sound / noise level meter. This meter has a built-in USB port which connects to a PC for downloading the sound level data recorded over a period of time. This is an ideal instrument for noise monitoring in factories, schools, business and traffic areas. This meter conforms to the IEC61672-1 Class 2 and ANSI S1.4 Type 2 standards.

With its internal memory and battery, this unit can record sound levels over a period of time as a standalone device. 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 and for your convenience.

The difference between the DT-8852 and DT-8851 is that the DT-8852 has internal memory, so the sound level can be recorded without a computer. The recorded data stored in the DT-8852 can be uploaded to a PC at a later time.
