Disappointing Performance of Sound Calibrator

The sound calibrator underperformed in measurements and proved to be unreliable. While it was easy to use, it didn't provide accurate readings, making it unsuitable for industrial and scientific environments. Thanks to my knowledge gained in practice, I was able to determine that the calibrator was faulty and not up to par with industry standards.

Pros
  • Easy to use
Cons
  • Inaccurate readings, unreliable

Cons
  • old

I need a calibration certificate for this calibrator please reply me

I need a certificate for this calibrator. I first bought this product to calibrate my Extech HD600 but I have found that this product does not come with a calibration certificate which I must provide for the project without which it is useless.

Pros
  • Sound and Noise Meters
Cons
  • Expensive
