The NL-52 and NL-42 were developed to
eliminate the trouble of reading instructions
when conducting measurements.
Large and easily viewable three-inch LCD color display.
The unit (except for the microphone) is water-resistant,
which means that it is unaffected by sudden rain showers.
You can use rechargeable batteries to help cut down on waste,
making this an environmentally friendly product.

Use of rechargeable batteries
In these new models it is possible to use rechargeable
batteries which make these meters environmentally-friendly.
24 hour continuous measurement ispossible
(when using dry alkaline batteries).
*Mounting the outdoor windscreen and rainproof windscreen
helps raise the water-resistant performance of the entire unit,
so that the microphone will also meet エPX3 specifications.
Continuous detailed measurements for one month
This meter can be used to conduct
long-term measurements, such as
environmental measurements.

Measurement functions
Simultaneous measurement of the following items, with selected time
processing or by A, C, Z-weighting.
Output voltage
Instantaneous sound pressure level: Lp
Equivalent continuous sound pressure level: Leq
Sound exposure level: LE
Maximum sound pressure level: Lmax
Minimum sound pressure level: Lmin
Percentile sound levels: LN (0.1 to 99.9 %, 0.1-increment steps, max. 5 values)
Processing (sub ch)
Instantaneous sound pressure level: Lp
Additional processing
In addition to main processing items, one of the following can be selected
for simultaneous processing:
C-weighted peak sound level: LCpeak
Z-weighted peak sound level: LZpeak
Maximum エ-time-weighted equivalent continuous sound level: LAエmax*2
The power average of the maximum level of each 5 second interval: LAtm5
The frequency weighting for the additional processing synchronizes with the frequency weighting
of the sub-channel, so when the sub-channel has A-weighting, LAtm5 can be selected.
When C-weighting (Z-weighting ) is selected, the additional processing LCeq and LCpeak
(LZpeak) are selectable.
