Product Name:High performance Sound Level Meter LA-7000 series
Manufacturer:ONO SOKKI
Availability:out of stock 0 item(s)
Product Code:LA-7000
More Information : The LA-7000 series is newly designed sound level meter which operation procedure has been greatly improved. The large color LCD and touch panel enable easy and intuitive operation.
Description
LA-7000 series allows “measuring while listening to sound” in addition to the original features of a sound level meter such as measurement and calculation.
By listening to the sound instantly at the measuring place, you can confirm condition of a target, perform sound source probing, and check that the sound is unfailingly being recorded. The LA-7000 series sound level meter is a great help for reliable measurement at measurement place where no mistakes can be allowed.
By adding various options, the LA-7000 series is able to be upgraded to a sound analyzer (frequency analysis) and a sound recorder*, performing more than just a sound level meter.
The measurement performance is substantially improved only using LA-7000 series which does multiple duties, such as sound measurement, sound recording, frequency analysis, and sound probing of abnormal sound.
By using LA-7000 series together with various analyses software, “waveform analysis”, “sound quality evaluation”, “fluctuation sound analysis”,and ”simulation of sound frequency” can also be performed.
Feature
4.3 inch (size for a smart phone), color
Displays overlapping graph with clarity
At one-touch operation
Recording and data storing are started just by
tapping with a finger.
Listening function
You can find the place from which the sound is occurring by turning the microphone (sound level meter) toward the sound. (It is also possible to listen only to the specified range of the sound.)
Compact
35 % of size-reduction in volume. Easy-to-hold design
Short lanyard for potable use
The short lanyard provided as an accessory prevents the sound level meter from slipping down.
Intuitive operation by a touch panel
It provides intuitive operation in easily understandable manner by even a beginner touching the sound level meter for the first time.
Home key
Home button leads you to the home screen.
Language selection
Selectable display language from English and Japanese
Capturing function
Capture image information by pressing power key and home key simultaneous.
Power supply from USB---Enables long-time measurement
12 hours of continuous operation: alkaline battery cells (size AA, 4 pcs.) used. Micro USB can be used. The USB consumption takes priority when alkaline battery cells are used in combination with an USB.
Windscreen correction function
Windscreen (standard accessory) does not require correction. (IEC61672-1:2013)
External power ON/OFF function---useful for built-in measurement
Easy ON/OFF operation by switching a battery box.
Listening function
DUAL mode & QUAD mode standard
Two or four of calculation values are able to be displayed on the screen. Useful when displaying multiple calculation values with different weightings, such as frequency weighting or time weighting.
Display example of QUAD mode
Listening function (Phone output) standard
This function enables measurement while listening to the sound.
•Effective for measurement in an anechoic room and remote place

Obedient standard, calculation item, measuring range and memory mode: It's same as a mode 1/1 octaves. Please refer to it.
RTA1/3 mode
This is one of the frequency analysis modes which displays frequency divided by octave band. Vertical axis represents sound pressure level (sound loudness), and horizontal shows frequency (sound pitch).
In this mode, it is obvious which pitch of sound is loud. Data comparison of RTA 1/3 data and MAIN data is available by overlapping drawing.
Filter1/3 mode
By using the octave band filter, you can listen to only the interested sound even in noisy environment.
It helps sound probing of abnormal sound. Data comparison of Allpass (all ranges) and Bandpass (specified band) is available.
