Decibel Meter
Bluetooth decibel meter for Android and iOS / Accuracy class 2 / live view / Battery and power adapter / PC connection with software / Frequency weighting A and C / Tripod mount / Measuring range 30 ... 130 dB / Optionally with ISO calibration certificate
The decibel meter has a measuring range of 30 … 130 dB and can be used where sources of noise are to be recorded. For example, the decibel meter is used to control the noise level on stamping presses, ventilation systems or on busy roads. With the push of a button, you can switch between the frequency ratings A and C on the Bluetooth decibel meter. With the data logger function of the decibel meter, up to 32700 readings can be recorded. For optimal positioning of the microphone, the decibel meter can also be mounted on a tripod.
With the Bluetooth interface, the Bluetooth sound level meter can be set up with an Android or iOS device. The measured values from the Bluetooth sound level meter live can be transmitted and saved via the free app. The values measured by the decibel meter can then be exported in CSV file format for further processing.
In addition to the Bluetooth interface, the decibel meter also has a mini USB interface. This allows the Bluetooth decibel meter to be connected to a computer. With the software for the Bluetooth decibel meter, the measured values can then be transmitted live to the PC and, if necessary, exported as a CSV for further processing.
With the included 12V DC power supply, the Bluetooth decibel meter can be used stationary. For mobile use, the Bluetooth decibel meter can be operated with a 9V block battery. The transport case enables safe transport for the Bluetooth decibel meter for mobile use. Optionally, the Bluetooth decibel meter can be equipped with an ISO calibration certificate.
