The HTC SL-1352 Sound Level Meter with data logging is a professional-grade instrument designed for accurate noise measurement across industrial, environmental, and research applications. It offers a wide measurement range of 30 dB to 130 dB, making it suitable for both low-level ambient sound and high-intensity industrial noise monitoring. With an accuracy of approximately ±1.4 dB and a resolution of 0.1 dB, the device ensures precise and reliable readings.

Equipped with A and C frequency weighting, the meter allows users to measure sound according to human hearing sensitivity or machine noise characteristics. It also features fast (125 ms) and slow (1 second) response modes for capturing real-time or averaged sound levels. The built-in data logging function can store a large number of readings, which can be transferred to a computer via USB for detailed analysis.
