英文 Introduction： The HS-5920 digital sound level meter is a pocket-sized noise measuring instrument designed for on-site inspectors. It is compact and lightweight, making it easy to carry and suitable for on-site instantaneous noise measurement in various scenarios such as health and epidemic prevention and urban traffic. The instrument uses an LCD display to clearly show the measured "A" sound level and is equipped with functions for maximum value retention and sound level setting, which can help users record and analyze noise data more accurately.
The HS-5920 digital sound level meter has a wide measurement range, with the low range (L) being 40dB—95dB and the high range (H) being 80dB—130dB. Its frequency range is 31.5Hz—8kHz, which can meet the noise measurement needs in various environments. It also features fast (F) time weighting and digital automatic display with a resolution of 0.1dB, ensuring the accuracy and real-time nature of the measurement data.
In addition, the instrument is equipped with a microcontroller that can process the measured data and can perform automatic and manual measurements of integral Leq sound exposure level LAE, noise dose DL, and instantaneous value LP. The automatic measurement time can be set to 10s, 1min, 5min, 10min, 15min, 1h, 8h, 24h, providing flexible measurement options for users.
