Extech Instruments, a major supplier of test and measurement equipment for the industrial marketplace, announces its SL130 Sound Level Monitor featuring both internal alarm illumination and external alarm output.  Designed for worker safety compliance, the SL130 is ideal for industrial environments where there is a need to generate an alert when sound levels exceed a pre-set limit. The SL130 features four built-in super brightLEDs that illuminate to visibly alert personnel when the area sound level limit has been exceeded.

Extech’s SL130 will continuously monitor the sound level in factories, plants, refineries, mills, or any other industrial workplacewhere noise level is a concern. The SL130 features user-settable high and low limit (30 to 130dB) indications along with an output to drive a remote warning indicator. Super bright red flashing or green LEDs can be read from 100 feet (30m) and maximum readings are recorded with date and time.  The SL130 Sound Level Monitor is compliant to OSHA and meets ANSI Type 2 accuracy specifications.

As a stand-alone device, wall or tripod mounted, Extech’s SL130 can be strategically placed to monitor noise levels for entire areas.  The SL130’s microphone rotates 180° for desired placement and is detachable to enable remote monitoring using the optional 15 ft (5m) microphone extension cable. In addition to the super bright red and green LED indicators the SL130’s large LCD display is also highly visible. With a programmable high limit set point between 30 and 130db’s, the SL130 is extremely flexible and settings can be quickly changed to meet varying needs.  The SL130 can also assist in eliminating noise factors by recording the time and date of maximum decibel level occurrences.  Certificates of Traceability to NIST are also available.

The SL130 also features a clock display, programmable start-stop time for extended battery life andrear panel controls to prevent unauthorized programming. The sound level monitor comes complete with an AC adaptor and microphone wind cover.
