Summary: HS5633B digital sound level meter is newly
developed according to the requirements of the new standard of
national sound meter, it has A, C” sound levels, and with functions
such as Max. maintenance”, sound level set, high and low range,
digital display of overload and oweload, AC and DC signal output,
etc.”, suitable for measuring environmental noise, traffic noise,
mechanical noise, electric noise, etc., also, it can be used on
measurement of architecture acoustics, electroacoustical, etc. This
instrument has stable performance, is convenient to use, with
advantages such as compact structure, small cubage and light
weight, especially suitable for on-the-spot measurement of various
noises. It accords with the requirements of IEC61627 <Sound
Level Meter> standard to Model 2 sound level. Main technical index and function: 1. Measuring range of sound level
meter:35~130dB(A), 40~130dB(C); 2. Frequency range: 20Hz~12.5kHz; 3. Frequency-weighted features: A、C weighting ; 4. Sound level set function: random set within
40~130dB; 5. Demodulation feature: virtual value; 6. Time weighting feature: F (fast) and slow (S); 7. Display: automatic display and circulation time of LCD is 1s, and the
resolution is 0.1 dB; 8. Maintenance feature: maintain max virtual value; 9. AC signal output: max virtual value is about 2V,
impedance is 600; 10. DC signal output: 0.3V~1.3V(change according to
0.1V/10dB, load impedance is 1M); 11. Power supply: 1 laminated cell of 9V, with input hole of outer
power supply. Other: Attachment: Regulator; Dimension: 246mm×70mm×30mm; Weight: 260g (with cell); Basic collocation: main machine, fan cover, screw driver, handbag. |
