Good used Quest Electronics Model 215 Sound Level Meter, Model M-7B Noise Dosimeter and Model CA-12B Sound Calibrator which will calibrate both the level meter and the dosimeter.  The Model 215 will measure sound level from 30dB to 140dB with five different weighted scales. The plastic lens is cracked but not loose and the plastic case latch is broken. The unit seems to work exactly as it was designed to.  The Model M-7B appears to work as designed but I am not real familiar with this device. It has some paint wear because it can be clipped to your belt and worn for an entire shift to measure long term sound exposure.  The CA-12B calibrator works as designed  and has two microphone adapters one of which fits the M-7B.  The 215 does not need an adapter. I have downloaded and printed manuals for these meters which will be included. All three have fresh batteries installed and I have been testing them for a week and am satisfied they all work properly.
