Sound Level Meters
Continuously monitor sound levels throughout the day using the Extech SL130W-NIST Sound Level Alert with NIST. Bright LEDs (red flashing or green) alert users when sound level is too high or too low - LEDs can be read from 30m (100ft). Wall, desk, or tripod mount with optional 15ft (5m) microphone extension cable for remote monitoring. User programmable high or low limit (30 to 130dB) with output to drive external relay module. Ideal for industrial, hospital, auditoriums, schools, and other areas where there is a need for being alerted when sound level reaches set points.
