Introduction
Thank you for selecting the Extech SL130 Sound Level Alert. Designed for wall mount, tripod
mount, desktop, or hand held operation this meter meets ANSI and IEC Type 2 Sound Level Meter
standards.
The SL130 offers a High/Low Alarm Limit feature where four two-color high intensity LEDs and a
large OVER indicator provide alarm alerts when limits are exceeded. The SL130’s physical Alarm
Output circuit can be used to drive the optional Alarm Module Kit to power a larger, remote
indicating device such as a “QUIET” sign.
Professional features include programmable A/C Weighting, Fast/Slow Response time, Max
Memory with time stamp, and a Clock display. The microphone can be rotated 180 degrees to
accommodate any meter location or it can be placed at a remote location using the optional Remote
Microphone Cable. A programmable ON/OFF time extends battery life to 30 days when
programmed 8 hours per day. The bright LED’s are functional only when the AC power adaptor is
used.
This device is shipped fully tested and calibrated and, with proper use, will provide years of reliable
service. Please visit the Extech Instruments website (www.extech.com
