Brief introduction: HS5660B (high/low) precision pulse sound level meter is a kind of (on) under low (high) measurement limit portable acoustic measuring instruments, read measurements at the same time by electric meter and liquid crystal display, can be used to measure and analyze the environment, such as machinery, vehicles, electrical noise, can also be used for architectural acoustics, such as acoustic measurements, especially its pulse can accurately measure the impact and short duration of the noise, such as gunfire, punching machine, such as explosion, typewriter noise. It can also be combined with HS5721 type 1/1 octave filter or HS5731 type 1/3 octave filter to form a portable spectrum analyzer with easy operation. Widely applicable to environmental protection, factories, schools, scientific research and other departments of low (high) noise measurement and analysis needs. Performance "jjg188-2002 sound level meter verification regulations" and IEC61627 "sound level meter" standard on level 1 requirements. Main technical parameters and functions: 1. Sound level measurement range :(2 * 10-5pa for reference) HS5660B (low) type A weight: 22 ~ 135dB, C weight: 32 ~ 135dB, linear weight: 40 ~ 135dB HS5660B (high) type A weight: 55 ~ 165dB, C weight: 65 ~ 165dB, linear weight: 70 ~ 165dB 2. Frequency range: 20Hz -- 20KHz; 3. Frequency meter weight: A, C meter weight, and F (linear); 4. Detection characteristics: real effective value and peak value; 5, time weight: fast, slow, pulse; 6. Overload indicator: LED LED; 7. Power supply: dc 6V, 4 1.5v high-energy batteries, and an external (220V) dc conversion power input hole; 8. Built-in 1000Hz sinusoidal calibration signal can be used for reference calibration; 9. With ac and dc output terminals, sound signals can be further processed and analyzed with filters and other equipment.
