Extech SL130G Sound Level Alert (Green Housing)
The SL130G can provide continuous monitoring of sound level. Ideal for industrial, hospital, auditoriums, schools and other areas where there is a need for being alerted when sound level reaches a user determined set point. Meter can be used for monitoring function only without LED alert. A programmable On/Off time extends battery life to 30 days when programmed 8 hours per day. Model SL130G-NIST is also available with a Certificate of Calibration Traceable to NIST.
Bright LEDs (red flashing or green) alert user when sound level is too high or too low — LEDs can be read from 30 meters (100 feet). Users can set the SL130G so the Red LEDs flash when the sound level is below the LO set point where people in the audience may not be able to hear. When the sound level is above the LO set point, the Green LEDs indicate the sound level is acceptable. You can reverse the Red and Green LEDs activation per user color preference.
Optional 15-foot (5-meter) microphone extension cable for remote monitoring.User settable high or low limit (30 to 130 dB) with output to drive an external relay module that can power a larger, remote indicating device such as a “Quiet” sign, or enable connection to an alarm system. Mount on a wall or tripod or set on a flat surface. Meets ANSI Type 2 and EN 60651 accuracy specs — compliant to OSHA.
