Sound Level Meter SL-4023SD Lutron
Sound Level Meter SL-4023SD Lutron – Class 2 SD Card Data Logging Acoustic Meter
The Sound Level Meter SL-4023SD Lutron is a precision digital acoustic measuring device engineered for environmental noise monitoring, workplace safety compliance, and industrial machinery noise testing. Designed to meet strict IEC 61672 Class 2 compliance standards, the Sound Level Meter SL-4023SD Lutron combines high-accuracy acoustic sensing with real-time SD card data logging capabilities.
As shown in the product image, the instrument features an ergonomic handheld casing equipped with an integrated 1/2-inch standard electric condenser microphone head, a large backlit LCD display, and intuitive tactile control buttons. A major operational advantage of the meter is its driver-free data management: acoustic readings with exact time stamps (year, month, date, hour, minute, second) record directly onto a removable SD card as standardized Excel spreadsheets for instant reporting and data analysis.
Key Features of the Sound Level Meter SL-4023SD Lutron
-
IEC 61672 Class 2 Compliance: Meets international acoustic safety and measurement standards for sound level meters.
-
Real-Time SD Card Data Logger: Records real-time sound measurements directly to an SD card (1 GB to 16 GB) in standard Excel format without needing dedicated software installation.
-
A & C Frequency Weighting: Features A-Weighting (simulating human ear response for environmental noise) and C-Weighting (near-flat response for industrial machinery and quality control testing).
-
Fast & Slow Time Weighting: Supports Fast mode (125 ms response) for quick dynamic bursts and Slow mode (1 second response) for evaluating average sound levels.
-
Auto & Manual Range Selection: Covers a wide range from 30 to 130 dB across auto-ranging mode or three selectable manual ranges (30–80 dB, 50–100 dB, 80–130 dB).
-
Convenient Data Functions: Includes Peak Hold, Data Hold, Max/Min Memory Recall, and custom sampling rate settings from 1 to 3,600 seconds.
Common Applications and Industrial Usage
The accuracy and data logging capabilities of the Sound Level Meter SL-4023SD Lutron make it suitable for diverse acoustic environments:
-
Occupational Safety (OSHA) Audits: Monitors workplace noise exposure levels in manufacturing plants, machine shops, and processing facilities.
-
Construction & Traffic Monitoring: Records decibel variations over extended monitoring sessions near building sites, highways, and residential areas.
-
HVAC & Environmental Noise Testing: Evaluates noise output from ventilation fans, compressors, air conditioning units, and industrial generators.
-
Acoustical Architectural Design: Assesses sound attenuation, room acoustics, and soundproofing effectiveness in auditoriums and offices.

Installation Guidelines and Best Practices
Operational Note: Always perform routine calibration before conducting critical safety or regulatory noise audits.
Outdoor Wind Protection: When taking measurements outdoors or in high-velocity airflow ducts, fit the optional foam windscreen (SB-01) over the microphone to prevent wind turbulence noise.
External Field Calibration: Align the meter with an optional standard 94 dB sound calibrator (e.g., Lutron SC-941) and adjust the built-in calibration VR using a small screwdriver.
SD Card Formatting: Format newly inserted SD memory cards directly through the meter’s advanced menu option (
Sd-F) to ensure file structure compatibility.
