Digital Termometer - Why Did This Happen????.....

[LeeBo]

I tested my digital thermometer as part of my pre-season check up. I cleaned it well and put it in a glass of ice water and it read 80 degrees. An hour later it read 60 degrees. I decided to buy a new one.

By the time I got back from Lowes' (with TWO of them) my old digital termometer was down to 40.

The ice had fully melted so I put more ice in and tested all three. The two new ones read at 39 and 37, the old one read at 37.

I added salt and all three immediately dropped. The new ones are at 37 and 35 respectively and the old one is at 35.

My question is this - after setting in the garage all year does the response time of digital propes get flat for the first few hours of use? I thought I had one bad thermometer and ended up with three good ones.

Still wondering why it read 80 and 60 degrees for the first hour of ice water though(???)....

lee,
I know when I put mine in to measure refrig temps, they are really slow to respond to the downward temp.
But--an hour? Not.

Fresh batteries?
Old "creaky bones" in the old one?
Don't know.

But, now you have three and are only about 6 short of the rest of us :lol: :lol:

Be sure to check them on the high side with boiling water also--much closer to chamber temps.

Good Luck.

I think you're correct about creaky bones.

I set up a glass of ice water and a boiling pot of water next to each other. I went back and forth numerous times. All three displayed the same temperature. However, the older thermometer was always the last one to get there.

It seemed to improve (a little) with the repititions.


Not a bad day. Ended it with three digital thermometers!
