HS-5633型通用声级计是一款便携式袖珍噪声测量仪器，广泛应用于环境噪声、交通噪声、机械和电气产品噪声的测量。该仪器内置单片机，具有体积小、重量轻、便于携带、数字显示等特点。其测量范围为40dB至130dB（A声级），频率范围为31.5Hz至8kHz。此外，HS-5633型声级计还具备最大值保持功能，能够有效记录测量过程中的最大声级。该仪器使用9V叠层电池供电，可连续工作8小时。

HS-5633B型通用声级计在功能上进行了进一步拓展，设有A、C频率计权网络，支持高低量程切换，能够满足不同场景下的测量需求。其最大值保持功能可记录测量过程中的最大瞬时声级，便于用户对噪声情况进行全面分析。该型号还具备交直流信号输出功能，方便与其他设备进行数据传输。HS-5633B型声级计采用三位半液晶显示器，分辨率高达0.1dB，更新速率约为每秒一次，能够清晰、准确地显示测量结果。

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.
