I have and have used the Radio Shack sound level meter for many years. The Radio Shack meter I have sitting next to me is the model you suggest; Cat. No. 33-2055. The Radio Shack sound level meter is the forum standard.
Recently, I decided I wanted better and purchased several different sound meters to try out and acquired a sound level meter calibration device so as to verify the accuracy of each of the sound meters being auditioned.This is the current sound level meter being used.
The difference, the one I suggest meets Type 2 standards and can be used for legal purposes (the Radio Shack model is unrated, type 3), reads <60dB (30dB), has a back lit panel and who's measuring microphone column fits standardized calibration devices. So, should one buy a calibration device, they can at home, easily, accurately and regularly, verify the calibration of their sound level meter. This as opposed to wondering or finding need to send the sound meter in for an expensive calibration check.
The device is spec'd to +/-2dB but calibrates out to -0.1dB.
(My only complaint with this unit, the panel back light turns off after five seconds and this timing can't be altered.)Calibration device used.
