I have other monitors but found my self monitoring with this one all the time. My doctor's office has the Welch Allyn but not the same model. I did take my monitor with me to my doctor office and check it with the one they have back to back believe me this monitor was neck to neck but my other monitors was very close. Hope this helps.

This monitor is the best I ever owned. I used OMRON and many others but this one I will stick with. Hope this helps.
