Id like to have one just for S&G's. :-)
Pretty much, anything will work. How anal are you about your readings?
As an example, my hangup are thermometers. Who calibrates these things? What standard is being used for calibration purposes? On the day the thermometer was calibrated, how happy was the employee and how much did they care about their professional calibration efforts. Does the manufacture really care about this stuff? It's been said, the best manufactured vehicles are autos manufactured on Tue, Wed and Thur due to being between hangover Mondays and I want out of here Fridays.
Continuing, how accurate are cheap thermometers vs lab grade thermometers and who calibrates and oversees the calibration of lab grade thermometers? And does a few degrees in error have any consequences in the grand scheme of life? If the thermometer reading is off, will water still boil at the assigned temperature and for correction purposes in answering the question, at what temperature does water boil, what's my elevation and who checked the accuracy of the contour lines on the topo map? With that in mind, enters sound meters, their accuracy, what are their calibration standards and what are the variables in calibration standards between a $20.00 meter vs $40.00, $80.00, or $120.00 meters? And did the tech really check the barometric pressure and make sure what the humidity was on that day or did they use yesterday's readings and gun-deck their log?
Enters my original question, how anal are you about these sorts of things? The point, if you care, you'll have to find out about sound meter calibration standards and find reviews to see what the differences are between a $20.00, $40.00, $80.00 amd $120.00 sound meter as you compare these against the price/quality levels of lab grade sound meters. Now we need to know, how do lab grade meters compare to each other? And what are the calibration standards for lab grade sound meters and how do these standards compare to those of the less expensive models? Did Sally do the calibration today or Pete, as everybody in shipping knows that Mike consistently provides the best calibration efforts because he doesn't party. In the end, how does anybody know who or what equipment manufacture they can trust to be telling the truth about the accuracy of their wares?
Me to self; Tom, it's a stupid thermometer."Jay Rant in Dogma" (Warning, lots of "F" language)
And to directly respond to your question, in the case of sound meters, I like to buy the $40.00 - $60.00 meters and if froggy, I'll go for the $129.00 meter, just because expensive measuring gear gives me that much needed false sense of security.
The good stuff runs in the $250 - $350 range and gives a +/- 1.5dB accuracy. Calibration devices are extra.
