The LCD BASS METER portable noise meter is intended for measuring the noise level and sound pressure at a low frequency. The source of measured signal can be provided by both industrial equipment and acoustic systems. The main advantage of this noise meter is complete autonomy of work. For carrying out measurements you won't need a computer; all data is processed and calculated in the device and depicted on its display. If it is necessary to receive more detailed information, such as spectrum or signal waveform, the device can be connected to a PC using USB port. Besides the Measuring the peak amplitude and its frequency mode, there is Clip detention mode that allows defining the harmonic distortion coefficient for preventing clipping (distortion) of signal with frequency up to 200 Hz. Usage of the external sensor based on the solid-state pressure transducer allows receiving results with high accuracy 0.1 dB.
The LCD BASS METER device is performed as the main unit and detachable sensor with vacuum suction cups for affixing in to any smooth surface, for example, glass. The length of the cable between the main unit and the sensor is 1-2 meters long that allows a user to be at some distance from the spot of measurement. The main unit has a support for placing it at an angle of 45°. At the main unit there are controls and two-line LCD display with micro-light for comfortable use of the device indoors or in the passenger compartment of a car. The device can operate from the battery inserted inside the case or from the external power supply such as mains supply at home (optional) or cigarette lighter in a car. The main unit has USB port for updating the device microcode and transmitting data from the device to the PC. The case of the noise meter and detachable sensor are made of the shockproof plastic material.
