EXTECH SL400NIST Personal Noise Dosimeter

The Extech SL400-NIST personal noise dosimeter, equipped with a USB interface and NIST calibration certificate, offers precise sound level measurements for occupational safety. It measures frequency-weighted noise exposure, peak sound levels (C and Z weighting), and logs up to 999,999 readings over sampling times from 1 second to 24 hours. Features include displaying sound levels, minimum/maximum values, Leq, and SEL, with adjustable criterion, exchange rate, and threshold levels. An optional 94 dB calibrator ensures ANSI-compliant calibration checks. Ideal for personal noise exposure and workplace noise assessments, it helps meet OSHA and IEC standards with Windows software for setup, data retrieval, and real-time analysis.
