Are the Ice-Water/Boiling water thermometer calibration methods accurate?

[alireza18feb]

I'm sick of it, seems like I can't find an accurate thermometer, I have 3 types of thermometers, digital, alcohol and mercury, none of them have the same reading in equal conditions, I wanna try the ice water/boiling water methods but I wanna see if this is accurate because the percentage of water contamination is different in different regions and that affects freezing/boiling point

Any suggestions?

I have no idea. But one hygrometer that is very common to use throughput out community is the Govee Smart Hygrometer. I’d recommend to try that one out of you haven’t already.

thank you...my hydrometer is alright, I just need to calibrate my thermometers

I’m pretty sure hydrometers are to measure the density of liquids. Hygrometer is for humidity.

oh yes you're right that was a mistype...i didn't get an answer tho

Mercury mostly is the most accurate ones. Better to choose the one with shortest range if available.

Ice and boiling water temperature is not accurate. Different locations and water can have different temperature

I'm living in a port city so I got the sea levels, but yeah, so what can I do?

@Kiki You have some experience/thoughts on this?

just got my second one in. Doing salt test the hygrometer is reading 1%low. The temp is 1 degree high. I've used my other one on all my hatches with good success. This one also doesn't take up egg space but you'll have to get the probe inside. They also make one without the probe.
