Detachable Probe Sound Meter, NIST Certificate

Detachable Probe Sound Meter with NIST Certificate of Calibration

Achieve precise sound level measurements with our Type 2 Detachable Probe Sound Meter, complete with a NIST Certificate of Calibration. This versatile instrument is engineered for accuracy and reliability, making it ideal for a wide range of professional applications, including OSHA compliance testing, environmental noise assessment, and industrial hygiene.

The meter features a unique detachable probe on a coiled cable that extends up to 3 feet (approximately 1 meter). This design allows you to take measurements in hard-to-reach areas while maintaining a safe distance and minimizing the operator's impact on the sound field for more accurate readings.

Key Features and Functions:

• Wide Measurement Range: Covers a broad spectrum from 30 to 130 dB with a high resolution of 0.1 dB and an accuracy of ±1.0 dB.
• Dual Frequency Weighting: Select between 'A' weighting (which mimics human hearing) and 'C' weighting (for measuring flat-response peak noise) to suit your specific testing requirements.
• Adjustable Time Weighting: Switch between Fast (125ms) and Slow (1s) time weighting to capture either peak noise levels or average noise fluctuations.
• Advanced Data Functions: Includes essential functions such as Hold, Peak Hold, and Min/Max recording to capture and analyze data effectively.
• AC Analog Output: Allows for connection to external devices like frequency analyzers, data loggers, or chart recorders for further analysis and documentation.
• Compliance and Certification: Meets the rigorous standards of IEC 61672:2013 and ANSI S1.4:2014 for Type 2 sound meters. It is also certified in compliance with OSHA regulations when used with an Acoustical Calibrator (like our model 850016).

Design and Usability:

The sound meter is designed for both handheld and stationary use. It features a built-in fold-out easel back for desktop viewing and a standard tripod screw mount for stable, hands-free operation. We recommend using a tripod to ensure the most stable and consistent readings during prolonged monitoring.

What's Included:

Your sound meter arrives ready for immediate use in a durable, foam-lined carrying case. The complete package includes:

• Detachable Probe Sound Meter
• Removable Windscreen (to reduce wind noise interference)
• Calibration Screwdriver
• 9V Battery
• User Instruction Manual
• NIST Certificate of Calibration

NIST Traceable Certificate of Calibration:

This meter comes with a Certificate of Calibration performed in our lab, confirming it meets or exceeds all published specifications. All calibration is performed using standards traceable to the National Institute of Standards and Technology (NIST) and includes complete documentation with a unique serial number, a certification label on the instrument, and a detailed certification testing report.
