HS-5633型通用聲級(jí)計(jì)是一款便攜式袖珍噪聲測量儀器，廣泛應(yīng)用于環(huán)境噪聲、交通噪聲、機(jī)械和電氣產(chǎn)品噪聲的測量。該儀器內(nèi)置單片機(jī)，具有體積小、重量輕、便于攜帶、數(shù)字顯示等特點(diǎn)。其測量范圍為40dB至130dB（A聲級(jí)），頻率范圍為31.5Hz至8kHz。此外，HS-5633型聲級(jí)計(jì)還具備最大值保持功能，能夠有效記錄測量過程中的最大聲級(jí)。該儀器使用9V疊層電池供電，可連續(xù)工作8小時(shí)。

HS-5633B型通用聲級(jí)計(jì)在功能上進(jìn)行了進(jìn)一步拓展，設(shè)有A、C頻率計(jì)權(quán)網(wǎng)絡(luò)，支持高低量程切換，能夠滿足不同場景下的測量需求。其最大值保持功能可記錄測量過程中的最大瞬時(shí)聲級(jí)，便于用戶對(duì)噪聲情況進(jìn)行全面分析。該型號(hào)還具備交直流信號(hào)輸出功能，方便與其他設(shè)備進(jìn)行數(shù)據(jù)傳輸。HS-5633B型聲級(jí)計(jì)采用三位半液晶顯示器，分辨率高達(dá)0.1dB，更新速率約為每秒一次，能夠清晰、準(zhǔn)確地顯示測量結(jié)果。

The HS-5633 General-Purpose Sound Level Meter is a portable pocket-sized noise measuring instrument, widely used for measuring environmental noise, traffic noise, and noise from mechanical and electrical products. Equipped with a microcontroller, it features a compact size, light weight, portability, and digital display. The instrument has a measurement range of 40dB to 130dB (A-weighted) and a frequency range of 31.5Hz to 8kHz. Additionally, the HS-5633 sound level meter is equipped with a maximum value hold function, which can effectively record the maximum sound level during the measurement process. Powered by a 9V battery, it can operate continuously for 8 hours.

The HS-5633B General-Purpose Sound Level Meter has further expanded its functions, featuring A and C frequency weighting networks and high-low range switching, which can meet the measurement needs of different scenarios. Its maximum value hold function can record the maximum instantaneous sound level during the measurement process, facilitating a comprehensive analysis of noise conditions by users. The instrument also has AC and DC signal output functions, which are convenient for data transmission with other devices. The HS-5633B sound level meter uses a three-and-a-half-digit LCD display with a resolution of 0.1dB and an update rate of approximately once per second, providing clear and accurate measurement results.
