17080052 PT# HS710-012 - Assess Peak Flow Meter Full Range Ea By Respironics, Inc -17080052

A bit confused, because I ended up finding my other one, and there is a variation of 30-40 points (It's the same model, but was sold by a different company and didn't have the extra markers on it. Now I don't know which is more accurate. Just have to use one and stick with it.

This Peak Flow works very well. I've had one for a couple of years and just felt that it was time for an upgrade.

Used as a test after asama scare to make sure getting air into lungs.

works great

Just as described. Happy with purchase. Would buy from seller again.

Reliable and consistent.

Great item

Great product!
