HY106A type acoustic exposure meter Introduction: The HY106A Acoustic Exposure Meter is a hand-held instrument with a standard extension cable. Its performance level is equivalent to that of a Class 2 sound level meter that meets the requirements of the national standard GB/T 3785-2010 and the international standard IEC 61672:2013 Sound Level Meter. It also meets the requirements of GB/T 15952-2010/IEC 61252:2002 "Personal Acoustic Exposure Meter Specification". It is suitable for on-site measurement of mechanical and electrical products noise, environmental noise, traffic noise, workplace noise, etc. It has a digital output interface with an 8G storage, which can be used as a noise data collector and can also be printed on site. Technical Parameters Performance level: GB/T3785 and IEC61672 Level 2 are equivalent. The measured evaluation amount is LP, Leq, LAE, L5, L10, L50, L90, Lmax, Lmin, LAeq8hn, EA, ND, Sd and the like. Microphone: HY247 2-stage engineering measuring microphone with a nominal diameter of 6.35 mm and free field frequency response. The nominal sound pressure sensitivity is 1 mV/Pa (nominal sound pressure sensitivity level is -60 dB, reference value is 1 V). Frequency range: 20 Hz to 12.5 kHz. Frequency weighting: A weighting. Time weighting: F (fast response). Measuring range: 65 dB to 140 dB. Display: 128 × 64 dot matrix liquid crystal display (LCD), resolution of 0.1dB, with overload, under range, battery voltage low alarm and other signs. Digital output: The output jack is a 3.5 mm two-channel headphone jack, RS232 serial communication port, output ASCII code, and modulation rate (baud rate) is 9 600 Bd. Power supply: 2 LR6 (No. 5) batteries, which can work continuously for 24 hours under reference environmental conditions. Memory: 8GB, SD card.
