Watch out

  • Check whether the listing includes the NIST certificate before ordering; the base model looks identical.

Why people pick it

  • Outputs a stable 94 dB or 114 dB reference at 1000 Hz with ±0.5 dB accuracy, per the maker's datasheet
  • Complies with IEC 60942 Class 2, the standard class for a field calibrator used to verify meter accuracy
  • Works with any sound level meter that has a 1/2 in microphone: place it on the mic, switch it on, and adjust the meter
  • The NIST variant adds a traceable calibration certificate, which supports calibration paperwork for audits and quality systems

Know before you buy

  • It is a Class 2 calibrator, not the tighter Class 1 reference some standards and certification bodies require
  • Only fits 1/2 in diameter microphones; 1 in microphone meters need an adapter the maker does not list
  • Runs on a 9 V battery, which is not as common as AA or AAA spares
