Details

This equipment is designed for conducting sound level measurements according to the IEC standard.

The NL-52 allows the simultaneous measurement of L_p, L_eq, L_E, L_max, L_min, L_peak, L_N with selected time weighting (F, S) and frequency weighting (A, C, Z) characteristics.

The base unit consists of the UC-59 1/2-inch electret condenser microphone, the NH-25 preamplifier, and the main unit. The preamplifier can be separated from the main unit thus enabling measurements at remote locations. The 3-inch backlit color TFT LCD display offers good visibility even in broad daylight.

Multiple languages are supported and the intuitive touch-screen operation offers an extremely user-friendly experience.

It comes equipped with a RS-232C port, a USB mini port, AC and DC output terminals, and an SD card slot for maximum connectivity.

Measurement results can be stored on the internal memory as well as on a SD memory card.

The unit can continuously operate for up to 24 hours on four size AA batteries. Nickel metal hydride rechargeable batteries can also be used to reduce waste. For long-term measurements the device can be connected to an external power supply.

Various optional programs are available, such as: continuous data recording, waveform recording, comparator output, octave and 1/3 octave band real-time analysis, FFT analysis, and reverberation time measurements.

Not to mention that the main unit is water and dust resistant, thus rendering your worries about sudden rains a thing of the past!
