Which one should I believe??

[Honey1]

I have two thermometers in my incubator.
The little glass one that came with my incubator (LG still air)
And a digital thermometer/hygrometer I got from walmart.
My glass one is reading 98 degrees and the digital one is reading 101 degrees.
Should I assume that the digital thermometer is more accurate?

 

[Leah-yes I know I'm crazy]

Can you swap the locations of the thermometers to see if it has something to do with placement? Good luck.

Lol. I have two digitals and now three tube style thermometers. I checked them all against each other, the ones that are the same are the correct ones, and the other ones, I do a little bit of math to get the right temp.

I would say you sould get two digital themometers so you can get the number between the two and get the most accurite. I use an acu rite and a springfeild. I have the same bator and the mercury does not read right. It os WAY off. Goodluck.

you have to calibrate one or all to see which is correct,, then adjust the readings on all of them to match the correct one..

stick them into a glass of water with as many ice cubes as you can fit into the glass.. It should read close to 32 degrees..

I guess I'll start by picking up a second digital thermometer tomorrow.
Thanks for all the help and suggestions.

Correct, but don't do it this way

For a start, it is very difficult to get the correct ice/water mixture, and have it at 32F. A degree either way really does make a difference. Also, a thermometer calibrated at 32F is not necessarily accurate at 99.5F, there are too many variables.

Do it this way:

You will have to get another themometer if you do it twiggs way so you sould just buy another themometer and throw out that mercury one, they are the worst!!!!! But you should just do that. And you wont have to buy clay and stuff. Goodluck.

101 + 98 / 2 = 99.5 is your temp. Thats what I do. Take the 2 temps add them up and divide.

A pack of modelling clay and a cheap medical thermometer (which they prolly already have) isn't much to be absolutely spot on with temp.
