Product Overview

The Lutron SL-4013 Digital Sound Level Meter is a professional-grade handheld sound measuring instrument designed for precise noise level monitoring in industrial, environmental, laboratory, and commercial applications. Unlike conventional sound level meters, the SL-4013 features a separate condenser microphone probe, allowing users to position the sensor independently from the display unit for greater flexibility when measuring sound in confined spaces, machinery, production equipment, HVAC systems, and hard-to-reach locations. The instrument measures sound levels from 30 to 130 dB with high accuracy and stability, making it suitable for occupational safety assessments, environmental surveys, quality control, research, and acoustic testing.

Built in accordance with IEC 61672 Class 2 standards, the SL-4013 supports both A-weighting and C-weightingfrequency networks along with Fast and Slow response modes to suit a wide range of measurement applications. The large LCD display includes Data Hold, Maximum Hold, Minimum Hold, and Memory Record functions, allowing users to capture and review critical measurement values with ease. An integrated RS-232 computer interface and AC analog output enable connection to computers, data loggers, and monitoring systems for continuous noise analysis and documentation.

Designed with a rugged ABS housing and advanced electronic circuitry, the SL-4013 offers dependable long-term performance while remaining lightweight and easy to carry. Whether conducting workplace noise assessments, machine diagnostics, environmental monitoring, or laboratory research, the Lutron SL-4013 delivers professional performance with outstanding reliability.
