If you happen to have one, a heat gun is also convenient for accurate measurements!
Okay. Originally i had it like that. But all that tells me is the heat mat is 121F so i freaked out and figured that wasnt how i was supposed to put it. So i should have one for ambient as well? Im currently loking at the acurite 00891 for both of my BPs.
