NX-43-RT

NL-X3-RT Octave Analyser Option

The -RT option for the NL series logger allows your NL-43/53/63 sound level meter to function as a Real Time 1/1 and 1/3 Octave Band Analyser. (Once the software has been installed to a meter the NX-43-RT SD card can be used as 512MB data and measurement storage card)

The -EX option is required to be installed before the NX-43RT

All versions of the NL series -RT option allow the user to log 1/1 and 1/3 octave data over any user defined interval with a wide range of parameters including the following:

• Instantaneous SPL: Lp
• Equivalent continuous SPL: Leq
• Sound Exposure Level: Le
• Maximum SPL: Lmax
• Minimum SPL: Lmin
• Percentile sound levels: Ln

All octave band measurements can be stored and the -RT option can be used in conjunction the Auto-Store function of the -EX option to allow an NL series sound level meter to become a long-term octave band logger.

The -EX option is required to be installed before the NX-43RT and the NX-63RT

NX-43-RT

The NX-43-RT option is compatible with the NL-43 and NL-53 sound level meters and provides 1/1 and 1/3 Octave Band Analysis with a bandwidth of 12.5Hz to 20kHz.

NX-63-RT

The NX-63-RT option is only compatible with the NL-63 sound level meters and provides 1/1 and 1/3 Octave Band Analysis with a bandwidth of 1Hz to 20kHz.

The NX-63-RT extends the low-frequency sound level measurement capabilities of the NL-63 sound level meter to include a low frequency spectrum analyser.
