TATUM Digital Sound Level Meter Noise Data Logger Outputs and Saves Measurement Results To a Computer Backlight Accuracy Sound Meter Real-time 0.1dB

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ----------------------------------------------------------------------

You can display real-time measurement results on your computer by connecting it to your computer using the included USB cable. Recorded data opened with dedicated software can be displayed as a graph or saved as an output in Excel format. You can also use it to create your own graphs and output data lists as PDFs. It can be used for noise measurement in factories, homes, transportation facilities, etc. ◇Notes on use When installing the driver on Windows 10, it is necessary to set up an unsigned driver. Unfortunately, we do not have any support for installing unsigned drivers. In our verification, it is not necessary to set up an unsigned driver on Windows 8 and Windows 7, but we will not provide support if you need to install an unsigned driver in the future. Thank you for your understanding. Measurement range: 30-130dB (A-weighted) 35-130dB (C-weighted) A characteristic: Used for ordinary noise measurement.
