Hello, the glass thermometer broke on our plasma thawer but it has the digital thermometer still and we can see the temp right on the front of it. Do I need to replace the thermometer or is the digital read good enough? It will alarm if the temp is too high or too low, I don't really see the use in the thermometer that just gets in our way and will most likely break again- its a boekel plasma thawer. 

 

TIA for your input!

As long as you validate/verify the digital, I believe annually is the requirement, you should be fine without a second thermometer hanging around waiting to get broken.   

I would consult your manufactures manual and follow their recommendations.

I use the integrated thermometers in my refrig, freezer. plt storage and thawing bath.

I verify with a NIST validated thermometer (q 6 months at my house).
