NL-X2

Rion NL-X2 Range

All Purpose Sound Level Monitoring from Rion.

The NL-42 and NL-52 Sound Level Meters are designed with a full colour three-inch LCD screen for ease of use.

They are water resistant, use rechargeable batteries and can record sound data for up to one month.

Both units are capable of measuring A, C and Z frequency weighted measurements with either F (Fast) or S (Slow) time weightings.

Along with the following values and statistics:

• Instantaneous SPL: Lp
• Equivalent continuous SPL: Leq
• Sound Exposure Level: Le
• Maximum SPL: Lmax
• Minimum SPL: Lmin
• Percentile sound levels: Ln (0.1% to 99.9% in 0.1 increment steps. Max 5 values)

The Rion NL-42 and NL-52 are water resistant to a rating of IP54.

Inclusions

• 1x Rion NL-42/52/62 Sound Level Meter
• 4x Alkaline AA cell Batteries
• 1x Microphone Windshield
• 1x Wrist Strap

Options

NX-42EX

By installing the Extended Function Program NX-42EX, the following functions are added to the NL-42/NL-52.

• Auto store function (including Maker function)
• I-time-weighted calculation function
• Comparator function
• Trigger function for measurement start
• LAN communication
• Continuous data output function
• Other optional programs such as Waveform Recording Program NX-42WR can be installed

NX-42FT

The NX-42FT software allows the unit to function as an FFT analyzer. In addition to sound levels (up to four conditions), FFT analysis processing and calculation of the Partial Overall (POA) values for specified ranges are possible.

NX-42RT

The NX-42RT software allows the unit to function as an octave and 1/2 octave real-time analyzer. In addition to sound level (up to 4 conditions), octave or 1/2 octave band analysis and calculation of the partial overall (POA) value of the specified band are possible.

NX-42WR

The NX-42WR software adds sound pressure waveform recording functionality. Sound pressure waveforms are recorded on the SD card along with the store data as a WAVE file in PCM format.

Logging Kit

The NL-X2 series sound level meters are available from ARL with an optional logging kit that extends the capabilities of the sound level meter’s to become a fully featured noise logger.
