Mr. Tom –
Small, accurate, inexpensive.
Great for multiple applications, these hygrometers are the perfect tool for letting me know the humidity inside my 3d printer filament enclosure. Combined with a model I found on the Bambu Labs website, the hygrometer fits neatly inside my AMS along with desiccant beads to keep the humidity low.

Works great, I have ordered this product 3 times already
I’m using it to print boxes to hold the filament for my 3d printer, the quality is good, the numbers visibility is great, the functionality is better than i expected because you can set them to show the temperature in C or F just just the push of the button in the back, as for durability well I have been using them for a few months already and they are all working very well.

Good way to test humidty and temp in tight spaces
Thermometer and hydrometer are both accurate, based on other sources for each I already had in my greenhouse. The LCD display is easy to read with a light source nearby, but no light up function limits their usefulness. The only negatives would be that the thermometer takes several minutes to register temperature changes – and since the inlet for air that is being measured is on the back, it is pretty easy to cover the inlet with the double-sided tape included with the package – rendering the thermometer function very slow/useless.Also, once you have taped the thermometer down, you will need to remove it to change the battery – so you will need more tape to re-fasten it. A small piece of double-sided velcro would have been better.I placed one of mine in my car to measure actual temp vs temp selected on my AC display, and it worked quite well.Note on my package – I only received one piece of two-sided tape with my package of two thermometers/hydrometers instead of two. I had some double-sided tape to use though, so no harm in my case.I recommend this as a small, cheap way to check temps and humidity whereever you need to.

Nice Accurate!
These are accurate, both humidity and temperature. They are pretty tough, also, and look good.

Great fit for 3D filament!
For the purpose of keeping 3D filament dry, these hygrometers are a great value and get the job done. While not perfectly accurate, they are more than sufficient to confirm that your desiccant is working and your filament is being stored at a safe, low humidity (20% or lower, ideally).They all come with extra batteries as well! Well

Ive bought these multiplr
Ive bought these before for 3D printing projects where I needed to manage humidity. These worked great. All 4 were within 1 percent on the readings

🤦🏻♀️🤦🏻♀️
My car is older and doesn’t have a temperature gauge so I thought this would work. Though it works accurately inside my house, unfortunately it ends up reading over five degrees off inside my car no matter where I mount it. I’m disappointed but going to keep them anyway just so I have a general idea of how hot it is. Great price but you definitely get what you pay for here.

affordable & accurate
affordable & perfect for monitoring conditions in my chick brooder. minus one star as one got splashed and stopped working – make sure it’s put somewhere it can stay dry!
