Key Features:

Dual-level calibration output (94 dB & 114 dB): Provides selectable reference levels to calibrate and verify sound level meters — useful for both everyday checks and high-level acoustic instruments.

1 kHz sine wave signal for accurate calibration: Outputs a stable 1 kHz tone to ensure your SLM’s microphone is reading correctly.

Compatibility with standard microphones: Designed for use with sound level meters that have 0.5-inch or 1.0-inch microphones — common in professional acoustic instruments.  

Meets international calibration standards: Compliant with IEC 60942 (1997-11) standard for sound calibrators — ensuring reliability and industry-recognized calibration quality.  

Rugged, portable housing: Durable die-cast aluminum body provides reliability and longevity; compact and lightweight for field or lab use.  

Easy operation — quick calibration check: Simple 3-position switch (OFF / 94 dB / 114 dB) and LED power indicator make calibration fast, clear and user-friendly.
