The REED Instruments R8085-NIST is a professional-grade, data-logging dosimeter engineered for industrial hygienists and safety managers who require documented accuracy.
Designed to monitor an individual’s sound exposure over an 8-hour shift, this compact tool calculates cumulative noise dose (%) and sound pressure levels (dB) in accordance with OSHA and CCOHS requirements. This model includes a Traceable Calibration Certificate with full data and uncertainties, providing the essential documentation needed for rigorous safety audits.
Type 2 High-Accuracy Sensor: Meets ANSI S1.4 and IEC 61672 Class 2 standards for sound level meters, delivering a high precision of ±1.0dB.
Dual Monitoring Modes: Simultaneously track both decibel levels (35 to 130dB) and personal %Dose to ensure comprehensive worker protection.
Fully Customizable Settings: Easily adjust the Criterion Level, Exchange Rate, and Threshold to meet specific local, federal, or organizational noise standards.
Advanced Data Logging: Capture and store up to 16,000 data points with time-stamping for detailed analysis via PC software and USB connectivity.
Rugged, Compact Design: Lightweight and tripod-mountable, it is built for long-term monitoring on active construction sites and manufacturing floors.
Occupational Safety Audits: Conduct mandatory 8-hour noise exposure studies for industrial and construction workers.
Hearing Conservation Programs: Verify that hearing protection requirements are based on accurate, certified data.
Industrial Noise Assessments: Monitor peak decibel levels near heavy machinery to identify high-risk zones.
Regulatory Compliance: Provide local and federal agencies with traceable evidence of workplace noise standards.
Environmental Impact Testing: Record acoustic levels for code enforcement, traffic studies, and environmental surveys.
