2.0 out of 5 stars Poor quality, 31 July 2011
This review is from: Sound Level Meter (30-130dB) - CEM DT-805 (DIY & Tools)
This sound level meter claims to conform to IEC 651 Type II but it does not. Its accuracy is terrible (nowhere near the +/- 1.5 dB claimed) and it varies depending on which mode you have it in (hi/lo range, A/C weighting, Fast/Slow time window). 50 would be good for a product that was any use but I recommend that you save your cash because this product isn't.

MarkC says:
Levels will appear to vary based on weightings, ranges and time windows that's the point of the alternatives - 90dB for 5secs is no problem but 90dB for hours at a time can cause issues. Weightings etc allow you to take this into consideration.

I understand time windows, time weightings, frequency weightings and dynamic ranges. However the variations that occur in different modes are far, far beyond what should be the case. It does not conform to the Type II specifications.
