Under DHHS regulations, the acceptable temperature range is 90-100F, which is measured at the specimen cup.
Ive emphasized the phrase "at the specimen cup" because you have to factor in the "temperature drop" when transferring the sub sample from the bottle and into the specimen cup.

For details on temp drop, read post #3 in this thread:

Burnt Toast Reviewed by Burnt Toast on . Urine subbing: What temp range is considered acceptable? Okay I promise this is the last question: Temperature Releated I searched the forums some more and I see that many people have varying opinions on what the "right" temperature is. I have been testing my Urinator with water and practicing for the past few days and it seems to be about 96 degrees pretty regularly. Is that too low? I am told though that the temperature strips on the outside of the urine containers are usually low by a degree or two? Should I worry? Maybe pack a heating pad in Rating: 5
