Product Outline
　Our new product TYPE 6226NW is a "waterproof sound level meter" with included extension cable, realized by particular kind of waterproof technology newly developed.
It guarantees trouble-free measurement even under rainy condition.

New development
Dedicated waterproof microphone
　 Due to the function of special filter which lets air and sound through preventing water from coming in, it allows to continue the measurement despite of drops of water on the top of the microphones after they are dried up.
The diaphragm or preamplifier would never be waterlogged or rust out.

They can be used outdoor.
・ Outdoor noise measurement under the condition of rainfall.
　（Aircraft noise, traffic noise, environmental noise）
・ Outdoor measurement of noise of running vehicle and measurement of engine room noise.
・ Noise level measurement in factories with steam generation
・ Environmental noise measurement at an indoor swimming pool or an aquarium.
・ Measurement of leisure cruiser noise or motorboat noise.

Measurement fruquency range
TYPE 6226NW is provided with newly developed waterproof
electret condenser microphone TYPE 7052NW, composed of
time-tested high precision electret condenser microphone
TYPE 7052 equipped with specified waterproofed grid.

The measurement frequency range is　20Hz～10kHz

TYPE 6226NW is conformed to JIS C 1502, and IEC 651・804 Type2.
The measurement frequency range of "sound level meter" specified in
JIS C 1502 is 20Hz～8kHz.

Linearity range
Linearity range is 100ｄB.
Extended range has made the setup of sound level meter quite easy.

Measurement items
A-weighted sound pressure level（LA）
The LA Measurement is made by selecting dynamic characteristics
"FAST"or "SLOW", and frequency characteristics "A".

The instantaneous sound level is displayed on the screen.
Numerical display is updated for "every second" and bar display
"every 0.1 second".

Sound pressure level（LC/LF）
The LC/LF Measurement is made by selecting dynamic characteristics
"FAST" or "SLOW", and frequency characteristics "C" or "F".

The instantaneous sound level is displayed on the screen.
Numerical display is updated for "every second" and bar display
"every 0.1 second".

Equivalent continuous A-weighted sound pressure level（LAeq）
The LAeq is Measurement is made by selecting dynamic characteristics
"FAST" or "SLOW", and frequency characteristics "A".
Measuring time can be chosen from
1 second, 3 seconds, 5 seconds, 10 seconds, 1 minute, 5 minutes,
10 minutes, 15 minutes, 30 minutes, 1 hour, 8 hours, and 24 hours.
Manual measurement is also possible.
During measurement, if the "Pause" button is pushed, the data for
3 last seconds or 5 seconds can also be deleted.
　　　
The progress value of LAeq is displayed on a display.
Percentile sound pressure level（LX）
Preparations of a noise level and an equivalent noise level are made.
「Start」KEY is pushed.
　　
Percentile sound pressure level (L05, L10, L50, L90, L95),
Sound exposure level (LAe),a A-weighted　sound pressure level (LA),
an equivalent continuous A-weighted sound pressure level (LAeq),
Maximum sound pressure level (Lmax), and minimum sound pressure
level (Lmin) are simultaneously measurable.

Data saving and PC communixation function
Memory function
Approx.10,000 samples : 1000 sets of results.

Calendar function
Built-in clock and calendar function installed.

Output signal
Provided with AC and DC signal output.
DAT recorder and level recorder can be connected.

The data recorded in the memory can be printed out by connecting a dedicated printer.

PC communication function
RS-232C function is equipped.
The data recorded in the memory can be transferred to PC in real time even under
the measurement.

Data communication is possible with all kind of computers with RS-232C function.
