Summary : 

HS5618A Integrating Sound Level Meter is an intelligent and portable meter which is integrated with A & C frequency weighting and can automatically meter equivalent sequent Leq, sound exposure level LAE, sound dose DL and instantaneous sound level LP on the basis of 10s,1min,5min,10min,15min,20min,1h,8h,24h and manual timing set(Maximum: 24h). Main performance is in accordance with IEC 61672 and JJG188-2002 sound level meter testing regulation level II.

HS5618A Integrating Sound Level Meter adopts 128×64 LCD display, menu operation,clock set, 24h clock display, auto-meter and store data functions. It can store up to 1000 single group of data and 64 groups of 24h time data and transfer these data to HS4784 for printing or computer through RS-232C port. These innovated functions can match many kinds of needs.

HS5618A Integrating Sound Level Meter is a well-designed multi-functional and high-automatic appliance. It can be used to measure sound level in terms of environment protection, factories, schools and scientific research, etc.
