sound level meter

HS6288Esound level meterIt is based on the countrysound level meterThe new standard requires the innovative development of a pocket sized intelligent noise measurement instrument. This instrument is convenient and reliable for measuring and reading, and can be widely used for measuring various types of noise in environmental monitoring, health and epidemic prevention, labor protection, schools, scientific research, etc.

IIHS6288Esound level meterMain technical indicators:
