TL5670B integral impulse sound level meter is precise acoustics measuring equipment. It meets JJG188-2002 sound level meter verification standard, IEC60804 and I type sound level meter standard of GB/T17181.
The measured data can be transferred to computers through RC232C connector and communication cable.
It can realize Lp real time communication output and airplane noise Lepn measurement.
It is widely used in environment noise measurement and industrial noise measurement, such as equipment noise, vehicle noise, vessel noise and electrical equipment noise.
It is also widely used in sound measurement field for departments, such as factories, enterprises, environment protection, labor hygiene, transportation, teaching, scientific research.
