Thông tin sản phẩm
- The function of TYPE 6236/TYPE 6238 can be extended quite easily to those such as measurement of various parameters for environmental noise, only by inserting option FFT Analysis Card into the card slot. Also, this equipment is provided with newly developed “0-dB function” for measuring ultra-low sound pressure level, symbolizing the next-generation sound level meter with extremely high resolution and reliability.
- TYPE 6236/TYPE 6238 is equipped with high precision electret condenser microphone(TYPE 7052NR/TYPE 7146NR) which ACO is most proud of.
- The measurement frequency range covers entire audible frequencies,TYPE6236:20Hz~20kHz,TYPE6238:5Hz~20kHz.
