Mini Hygrometer Thermometer, 3 Pack LCD Digital Temperature Humidity Meter Thermometer Humidity Gauge Meter for cigar humidor Reptile Incubator Poultry office bedroom living room (Black)

If you are after something to be 100% accurate then maybe they aren't for you, mine were all within 1.5c of each other, humidity was all within 2%, used them for storing 'stuff' in Jars at the right humidy and temp so they worked perfectly

Just a slight difference

Don’t buy this junk, not even close to accurate. Can’t believe Amazon allow these cowboys to sell this rubbish.

Got 3 in parcel didnt think to check all 3 1 appears to be melted and numbers on dial aren't readable other 2 are perfect backs do slide alittle thou cant really complain for price really

I brought these for making a drying box for 3D filament and shoes, etc. Their lowest reading is 16-19% but that's to be expected as accurately reading very low humidity requires a significantly more expensive sensor. The humidity reading does change quite rapidly, it seems to respond in the 10s of seconds range or quicker; the thermometer reading takes many minutes to stabilise on the other hand. The three devices gave identical readings, so they were consistent. I'd love if they read down to 1% but for the cost they let me know when the silica gel is in trouble and if the things I've put in the boxes are really damp; they look awesome in the large tupperware boxes too :)

So as seen in the picture, they all have a different reading.I only really needed 2 and wanted a back up, so I'll be using the ones that read the closest.When in my reptiles enclosure, they read pretty much the same as my previous ones.

Good value but the thermometer isn’t very accurate. Does the job but not for anything important/precise.

I find the three small devices VERY useful to help us keep the temperatures good in the rooms of our flat during cold weather.
