Thermometer Hygrometer Accuracy

[dr del]

Hi,

You had the right idea but didn't take it to the next level.

Pick one to "trust" ( the ones sold in phamacies for human temp taking should be fine ) put them all in the same place as you did before but this time write the difference to the control thermometer on them with a marker or a sticker.

Now you can use all of them.
