The REIDEA thermometer/hygrometer (top right) was my first ‘reference’ hygrometer, i.e. I took it to be correct. Then I bought a few others, and it’s at least 7% higher than all of them, including the $1.25 cheap-ass units from Amazon, and an Inkbird humidity controller.
I used the REIDEA to ‘calibrate’ (i.e. a sticker on the back listing its deviation from the ‘correct’ reading, so I could adjust the humidity as needed) the little el cheapo models, and that’s what I’ve been using in my cheese ripening boxes.
Maybe I'm blaming it for my own lack of skills (a poor workman blames his tools), but honestly, there are enough variables in cheesemaking that you shouldn't have to worry about something like this
The REIDEA unit is no longer available, unsurprisingly.
