DISCONTINUED ITEM-Recommended Replacement: Extech SL400 Personal Noise Dosimeter with USB Interface

The Extech SL355 is a compact, lightweight dosimeter designed to test noise exposure and provide noise surveys for compliance with OSHA, MSHA, DOD, ACGIH, and ISO standards. Featuring a USB interface and Windows-compatible software to control setup and retrieve stored events or analyze measurements, this dosimeter provides adjustable Criterion Level, Exchange Rate, and Threshold, and can measure frequency weighted noise exposure and peak sound level simultaneously. Comes with belt clip and clip-on 0.5 in. microphone with 2.6 ft. (0.8-meter) cable, 3 AAA batteries, mini screwdriver and carrying case, PC software, USB cable, user manual.

The SL355 Sound Level Meter (SLM) displays real-time sound pressure level (SPL) readings along with LEQ, SEL, and elapsed time as a typical type 2 SLM would. The SLM has selectable measurement ranges: 60 to 130 & 70 to 140dB, ‘A’ and ‘C’ frequency weightings, Linear ‘Z’, and ‘C’ Peak weightings, Fast & Slow response time settings, and an adjustable energy exchange rate (Q).
