The Extech SL400 is a compact, lightweight personal noise dosimeter with a USB interface, designed to test noise exposure and provide noise surveys for compliance with OSHA, MSHA, DOD, ACGIH, and ISO standards. It measures frequency-weighted noise exposure and peak (C, Z) sound level, and includes PC software to control setup and retrieve stored events or analyze real-time measurements.
For employees who are exposed to loud noise, sound level monitoring is essential to determine what protective measures are required. Worn on the body, the SL400 performs OSHA and IEC noise accumulation surveys to determine total sound exposure over an 8-hour period. Listed applications include personal accumulated noise exposure measurement, workplace noise assessment, and OSHA and other regulatory agency compliance.
ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.
Extech Instruments became part of FLIR Systems in 2007, and FLIR Systems was subsequently acquired by Teledyne Technologies in 2021.
