Type 1 Sound Meter

Professional Type 1 Sound Level Meter

This professional-grade sound meter is engineered for precision, meeting the stringent requirements of IEC 61672-1:2013 Class 1 and ANSI/ASA S1.4-2014/Part 1 Type 1. It is the ideal instrument for applications demanding the highest level of accuracy, including environmental noise assessments, occupational health and safety compliance (OSHA), and product noise certification.

Key Features:

• High Precision Measurements: Provides reliable and repeatable sound level readings across a wide range from 30 to 130 dB with a fine 0.1 dB resolution and an exceptional accuracy of ±0.7 dB.
• Flexible Measurement Modes: Equipped with user-selectable fast and slow time weightings to accurately capture both fluctuating and stable noise sources. The peak hold function allows for easy identification of maximum sound levels.
• Versatile Outputs: Features an AC output, enabling the meter to connect to external devices like data loggers or frequency analyzers for advanced signal processing and recording.
• Simple Calibration: An internal calibration adjustment allows for quick electronic verification. For full compliance with standards like OSHA, the meter can be acoustically calibrated using our Acoustical Calibrator (model 850016) or an equivalent device.
• N.I.S.T. Traceable Certification: For applications requiring documented accuracy, an optional N.I.S.T. Traceable Certificate of Calibration is available. This certificate verifies that the instrument was calibrated against standards certified by the National Institute of Standards and Technology.

Ready for Field Use:

The meter comes as a complete kit, housed in a durable, hard-shell carrying case for ultimate protection. The package includes:

• Type 1 Sound Meter
• Detachable windscreen for minimizing wind interference
• Calibration screwdriver
• Two 9V batteries
• Comprehensive instruction manual

For optimal stability and the most accurate readings, we recommend using a tripod with the integrated mount, especially during long-term monitoring.
