3 thermometers

[ChickenCanoe]

I use a meat thermometer and it is the most accurate I know of for the price.

I used to have 5 or 6 thermometers and none agreed. One was a Brinsea Spot Check but I didn't believe it. When I got the pocket digital from Thermoworks, it agreed exactly with the Spot Check. I threw all the others away.

My other hobby is beer making which requires calibration also I have maybe 15 thermometers in my house that have all been calibrated

So all these calibrated therms are not matching?

The other beer thermos dont have humidity attached at all as it is an unimportant issue for beer

I will put one in there today if 8 can find an u used one as I generally have several batches of beer going at once

I use separate devices for measuring temp and humidity.
An accurate thermometer is the most tool for incubation, IMO.

Humidity can be off by a bit but not temperature.

update on temps

so, I moved all the thermometers into almost the same exact area to get a better idea what Im dealing with

The digital (from incubator warehouse which I don't think I can calibrate) is in the 101 to 101.8 range I seem to trust this one the least

Meat therm which is about 1 inch higher than the other 2, and is calibrated for many years from making beer is moving between 99.4 and 100.2 I don't see it moving much from that range I trust this one a lot, cuz I have had it for a LONG time and has never failed me ever, even when I culture yeasts

The therm on the unit is showing about 99.3 to 99.7 This one controls the actual heater, so I pay attention to it either way

I think the digital is wrong a little, and since its a still air unit, that temp isn't making me worry too much

so, im gonna go ahead and let it ride got about 90 more eggs saved up for incubator #2, but wont use them all Only gonna pick the ones in the 16-18 range for weight and let those go into the chicken trays, and see what happens

How do you calibrate your therms?

 

[tennesseequail]

with ice water is how I was always taught when doing beer I cant imagine its much different, no?

The one rom Incubator warehouse however I don't think can be calibrated I read online about it, and since I have no idea where the actual sensor is on it, and I don't think submerging it in icewater will help, i guess they come already calibrated ?

Yeah, I guess that can work, not accurate IMO....we're not incubating at 32°F...and most bator therms don't even include that temp in their ranges or operation.

Why I compare(it's not really 'calibration') my therms to a human medical thermometer.

This is how I test mine:

The temps i need for beer are in the 170 to 200 range but calibration. Has to take place at an absolute

I think even.most instructions have it being done such.
