Can you calibrate these? Tube thermometers you can by putting in ice water and sliding tube as need be.

I don't believe these can be calibrated. I have two side by and the temperature remains within one degree of each other but the humidity difference is usually 10-15%.

Does this have a calibration feature? I want to be able to periodically recalibrate.

No, it does not. I find it to be quite accurate, though! I would imagine that you could just remove the battery and re-insert it to recalibrate. But manually, no calibration feature. I have baseboard heat with no thermostat so this really helps me know room temperature and humidity. Good product!

Can you change celcius to Fahrenheit? I got mine and it’s reading celcius, prefer Fahrenheit

Ours is on Fahrenheit so you must be able to change it.
