Sound Level Calibrator Decibel Meter Calibration - Dual 94dB/114dB

In this review the Sound Level Calibrator is judged as a focused tool for audio professionals and technicians who need a quick, reliable reference tone when checking measurement microphones. Its single biggest reason to buy is straightforward: it supplies two precise output levels, 94dB and 114dB, so a user can verify meter response across common test points without complex setup. The unit ships calibrated to deliver 94dB at sea level and fits common microphone sizes, making it a practical companion for field checks and routine lab work.

Key Features

• Dual output levels: The 94dB and 114dB settings let you validate meter linearity and response across two widely used calibration points.
• Pre-calibrated 94dB: Calibration to produce 94dB at sea level means fewer initial adjustments and confidence in baseline accuracy out of the box.
• Universal microphone fit: The design accepts both 1 in and 1/2 in microphones and includes a 1/2 in adapter for immediate compatibility with different measurement mics.
• Long battery life: Approximately 100 hours of operation reduces downtime and the need for frequent battery changes during extended site work.
• IEC942 Class 1 conformity: Meeting this standard assures users that the device adheres to recognized precision requirements for calibration tools.

Who It's For

The calibrator is best suited to live sound engineers, acoustic technicians, and test lab technicians who regularly verify the performance of sound level meters and measurement microphones. Its portability and simple two-level output make it useful for quick field checks and routine maintenance of measurement rigs.

Those who need an all-in-one laboratory grade calibration system with adjustable SPL across a wide continuous range or traceable multi-point certificates may want a more sophisticated calibrator with broader features. For straight-forward verification and everyday use, this unit is a practical, cost-effective choice.

Pros & Cons

Pros

• Provides two common and precise output levels for quick verification of meter accuracy.
• Pre-calibrated 94dB output reduces setup time and increases confidence in initial readings.
• Accepts both 1 in and 1/2 in microphones and includes an adapter for easy compatibility.
• Long battery life of around 100 hours supports extended field use.

Cons

• Only two fixed output levels are provided, so it is not a substitute for multi-level, fully traceable laboratory calibrations.
• Specification details such as environmental limits or supplied calibration certificate are not detailed in the product literature.

Specifications
