The instrument meets ANSI and IEC 61672-1 Type 2 standards and records measurements directly to an SD card in Excel format, which the datasheet describes as enabling easy transfer to a PC for analysis. The SDL600 is positioned by Extech for compliance with OSHA and other local and national noise ordinances under the IEC 61672-1 Class 2 accuracy standard. Typical use cases involve sound level measurement and data logging applications where time-stamped records of sound pressure level need to be retained for later review. ValueTronics stocks and ships Extech instruments from our 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Each unit moving through our facility is handled by our team rather than passed through a drop-ship arrangement, which means availability is real, condition is verified before shipment, and your point of contact can answer questions about the specific unit you are receiving. ## Brand Heritage Extech Instruments operates as part of FLIR Systems, and the SDL600 datasheet carries a 2007-2016 copyright in the name of FLIR Systems, Inc. FLIR Systems was acquired by Teledyne Technologies in 2021, placing the Extech brand within the Teledyne FLIR portfolio. ## Compare Other Models in This Series The SDL600 is offered in two configurations identified in the datasheet's ordering information: the standard SDL600 Data Logging Sound Level Meter and the SDL600-NIST, which is the same instrument supplied with calibration traceable to NIST. Both configurations share identical measurement specifications, the same 30 to 130 dB range, the same ±1.4 dB basic accuracy, the same ANSI and IEC 61672-1 Type 2 compliance, and the same SD card data logging capability. The distinction is the calibration documentation supplied with the unit at the time of shipment. Each new configuration listed below is its own product page with condition-matched pricing. The SDL600 and SDL600-NIST are functionally the same instrument and differ only in whether NIST-traceable calibration documentation is supplied with the unit. The selection between SDL600 and SDL600-NIST is governed by whether the receiving organization requires NIST-traceable calibration documentation at the time of delivery. Quality systems that require calibration traceability for measurement instruments will typically specify the SDL600-NIST configuration. Both configurations are otherwise identical in measurement performance, accessories supplied (6 AA batteries, SD card, wind screen, and hard carrying case per the datasheet), and accessory compatibility with the 407744 and 407766 sound calibrators and the 153117 and UA100-240 AC adaptors.
