The Extech SL130W is a continuous sound level alert and monitoring system designed for UK health and safety professionals, facility maintenance teams and HVAC engineers who need to track and control noise levels in industrial, educational or healthcare environments.
With its bright LED alerts and programmable sound limits, it helps users maintain safe and compliant sound levels in accordance with OSHA and UK noise exposure standards.

Simple to install and easy to read from up to 30 metres away, the SL130W provides real-time noise level alerts through green and red LED indicators.
It’s perfect for noisy workspaces, quiet zones, classrooms, or production areas, wherever consistent sound monitoring is needed.
Technicians can mount it on a wall, desk or tripod and even connect it to an external relay or remote microphone for flexible operation across large areas.
