Jeanna,
I have the same one you posted. It measure FVC and FEV1. I bought it 4-5 years ago at a drug store for about $100. I find the FVC isn't very accurate but the FEV1 is decent. I usually blow a few points higher at the clinic so I don't mind that at all. I also found the way to 'cheat' on this device but overall it's a pretty good predictive tool to keep around.
