Inaccurate readings, poor quality instrument

Industrial and Scientific enthusiasts beware! This Sound Decibel Calibrator Calibration Meter is an absolute letdown. I purchased this instrument for on-site noise level measurement for my industrial work. To my disappointment, it's inaccurate readings made it unusable, making it a big waste of money. However, it's compact size is a plus point, but it's poor quality mechanics make it an unreliable tool for any professional work.

Pros
  • Precise calibration for accurate sound measurements.
Cons
  • Requires additional equipment to be regularly calibrated, which can result in added cost and inconvenience.

Too expensive

Very, very expensive for a job, almost twice the price of my meter! And it's the cheapest calibration tool ever! My sound level meter is calibrated with a very stiff screw potentiometer so readjustment is probably not necessary. I've checked the calibration a few times since the original calibration and my meter isn't working. So now this tool just sits there. If I get another counter I can use it again. It works, and pretty well. However, this is a rarely used tool and I don't think the cost…

  • Industry and Science

  • Discontinued model

Cheap and accurate!

I recently purchased an Extech SL510 Class 2 Sound Level Meter and wanted to make sure the factory pre-calibration was correct. This Class 2 calibrator is one of the cheapest and works well - it fits a 1/2" mic and appears to be accurate: the SL510 delivered just 0.1dBA of the 94dBA sound produced by the calibrator. I have corrected the difference and will probably recalibrate the sound level meter (if necessary) every 3-6 months. Given that most calibrators are quite expensive ($300+), this…
