Calibrate Your Br�El & Kj�R 2673

Your Br�El & Kj�R 2673 Doesn’t Need Guesswork.

It Needs Calibration — Without the Runaround.

Your organization trusts the Br�el & Kj�r 2673 Microphone Preamplifier to tell you the truth.

Br�el & Kj�r 2673 Microphone Preamplifier Calibration

Quick Overview

  • What it is: High-quality microphone preamplifier for acoustic measurement.
  • Typical Use: Integrates with condenser microphones for sound level meters, test systems, and laboratory research.
  • Status: Discontinued/Obsolete (production ended, replaced by newer models like the 2670 and 2671).

A Br�el & Kj�r 2673 Microphone Preamplifier doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 2673, the specification limits, and the standards behind them. 

Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.

FAQ

Calibration should typically be performed annually, but frequency may depend on the organization’s quality policy, regulatory requirements, or manufacturer's recommendations.

Calibration may be necessary if there's a drift in measurement accuracy, after repair or replacement of parts, if exposed to adverse conditions (shock, moisture, or extreme temperatures), or if calibration is due per scheduled maintenance interval. Periodic verification against a known standard or reference can prompt recalibration if deviations are detected.
