 一、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.
