ACO รุ่น Type-6226H เครื่องวัดระดับเสียงความถี่ต่ำความดันเสียงสูง,High sound pressure low frequency sound level meter,meas.range:60〜164dB

In convenient construction sites such as tunnel construction and explosives training, blasting sounds can measure 164dB (3170Pa) to high sound pressure drop frequency sound pressure level (1Hz~8kHz) It can be used indoors and outdoors. Due to the special anti-drip treatment, it can be used just by covering it with a microphone. It is smaller in size than traditional all-weather windshields, easy to use and inexpensive

At convenient construction sites such as tunnel construction and explosives training, blasting sounds, etc. can measure 164dB ( 3170Pa ) to high sound pressure drop sound pressure level ( 1Hz~8kHz ) It can be used indoors and outdoors. Due to the special drip-proof treatment, it can be used just by covering it with a microphone. It is smaller in size than conventional all-weather windshields, easy to use and inexpensive. When used in combination with an extension cable (waterproof type), it is also effective in comfortable measurements, such as when the main unit is indoors and the microphone part is outdoors where the target sound source is located

• Linear range
  

The linear range is 100dB wide, making it easy to set up the sound level meter. [ Newly developed ]

•  Measuring frequency range

TYPE 6226H

Adopt high sound pressure electret condenser microphone.

The measurement frequency range is 1Hz to 8kHz

•  Measurement items

Noise Level (LA)

The noise level can be measured by setting the operating characteristics to " FAST or SLOW " and setting the frequency correction to " A characteristics".

The display shows the instantaneous value of the noise level.

The digital display is updated every "second" and the bar display is updated every " 0.1 second".

•  Sound pressure level ( LC / LF )

The sound pressure level can be measured by setting the operating characteristic to " FAST or SLOW " and setting the frequency correction to " C characteristic or F characteristic ".

The display shows the instantaneous value of the noise level.

The digital display is updated "every second" and the bar display is updated "every 0.1 second".

•  The equivalent noise level (LAeq)

The operating characteristics are set to "Fast or Slow" and the frequency correction is set to " A Characteristics".

Then select the measurement time.

The measuring time can be selected

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.

If you press the "Pause" button during measurement , you can also delete the latest 3 seconds or 5 seconds of data.

The display shows the progress value of LAeq .

• Hourly Rate Noise Level (LX)

Prepare noise levels and equivalent noise levels.

Press the "Start" key.

The hourly noise level ( L05 , L10 , L50 , L90 , L95 ) and single noise exposure level ( LAe ), noise level ( LA ), equivalent noise level ( LAeq ), maximum value ( Lmax ) and minimum value ( Lmin ) can be measured simultaneously.

Storage function, communication function with computer

Storage function

About 800 pieces of data can be recorded.

Calendar function

Equipped with clock function and calendar function.

Output signal provided

AC signal and DC signal output terminals.

You can connect a DAT recorder or a level recorder.

You can also print the data recorded in the memory by connecting a dedicated printer.

• Communication function with personal computer is installed

Not only can the data stored in the memory be transferred to the personal computer, but the measured data can also be sent to the personal computer in real time.

Any computer equipped with RS-232C function can perform data communication.

• The linearity range has been widened by 100 dB, making it easier to set up the sound level meter.
• Newly developed electret condenser microphone for high sound pressure, measuring frequency range 1Hz to 8kHz
• Noise levels can be measured by setting the operating characteristics to "FAST or SLOW" and the frequency weighting to "A-weighting."
• Sound pressure level can be measured by setting the operating characteristics to "FAST or SLOW" and the frequency weighting to "C or F weighting."
• The display shows the instantaneous sound level value, with the digital display updated every second and the bar display updated every 0.1 seconds.
• It is also possible to measure equivalent sound pressure level (LAeq) and percentile sound pressure level (LX), etc.
• The memory function can store up to 10,000 data items. It also has a clock and calendar function.
• It is equipped with output terminals for AC and DC signals, and you can also connect a dedicated printer to print out the data recorded in the memory.
• Equipped with RS-232C function. Data stored in memory can be transferred to a PC, and measurement data can be sent to the PC in real time.
• For construction sites where there is splashing water, it can be combined with the optional small all-weather windscreen (Φ75).
