Sound level monitoring is critical in determining whether protective measures are needed for employees who are frequently exposed to loud noise. Use the Extech SL400 dosimeter to conduct noise surveys that meet OSHA, MSHA, DOD, ACGIH, and ISO regulations. An SL400 noise accumulation study can measure total sound exposure over an 8-hour period. This compact, lightweight dosimeter may also function as a sound level meter, logging up to 999,999 values with sample periods ranging from 1 second to 24 hours. An optional 94 dB calibrator allows you to execute ANSI-compliant pre- and post-calibration checks. The SL400 includes with PC software for controlling setup, retrieving recorded events, and analyzing real-time measurements.

The SL130W is a sound level alert with an alarm that allows for continuous monitoring of sound levels. Ideal for use in industrial, hospital, auditorium, and educational settings where sound levels must be monitored. Bright LEDs (red flashing or green) inform the user when the sound level is too high or too low; the LEDs can be read from 30m (100ft). You can program the SL130 so that the RED LEDs blink when the sound level falls below the "LO" set point, where persons in the audience may be unable to hear. When the sound level exceeds the "LO" set point, the GREEN LEDs signal that it is acceptable. You can reverse the activation of the red and green LEDs based on the user's color preferences.
The SDL600 saves data to an SD card in Excel format. High precision (±1.4dB) fulfills ANSI and IEC 61672-1 Type 2 standards. The measurement range is 30 to 130 dB. Automatic or manual ranging. AC analog output to connect to an analyzer or recorder. Large, backlit LCD display. Stores 99 manual readings and 20M readings on a 2GB SD card. Dataloggers date and time stamp readings and store them on an SD card in Excel format for easy transfer to a PC. The sample rate can be set by the user between 1 and 3600 seconds. Includes Min/Max, Data Hold, and Auto Power Off capabilities. Comes with 6 AA batteries, an SD card, a wind screen, and a protective carrying case.
