Is it the right fit?
Who the KR-TH1 hygrometer suits
A good fit when
Dry air cracks a guitar. Damp air grows mould in a closet. The KR-TH1 shows both numbers at a glance, with a face that reads dry, comfort or wet.
It refreshes every 10 seconds, so it keeps up in a greenhouse or beside a humidifier. Small digits show the highest and lowest readings so far. Stand it on a shelf, hang it on a nail or let the magnet hold it to the fridge.
Know before you buy
- It has no backlight.
- It does not connect to a phone.
- Accuracy is ±1°F and ±2 to 3% RH. That is fine for a room and too coarse for a lab.

What buyers say about the KR-TH1 hygrometer
5 out of 5
My office is always too cold or too hot. It's nice to be able to tell maintenance what the temp is in addition to the humidity (which makes a huge difference). Great product.

I like the look of it, I like the features and how it has both temperature and humidity and even keeps track of the highs and lows. I also like the large easy to read numbers and text. The temperate reading is accurate and matches other thermometers I have. The humidity is reading a little lower than my other humidity meter but I'm not 100% sure which one is more correct but, either way, it's close enough.You can place it on a table using the built-in kickstand. You can place it on your fridge or other metal surface being it has built-in magnets on the back although the magnets seem to be a little on the weak side so it might slide or fall off too easily if you hit it. You can also mount it on the wall using one of the 2 included screws. It even came with 2 plastic mollies for better securing the screws into drywall. I have mine mounted on the wall, using one of the included screws. I didn't bother with the molly.My only complaint whatsoever, and it's a small one, is that the background isn't as white in person as it looks in the picture. The manufacturers picture shows the high contrast between the black LCD numbers and the white background of the LCD. However, in real life, the contrast is much less as the background is not so bright white. It's a little less white. If you look at the real life pictures that some of the reviewers posted, you'll see what I mean. However, it's really not that bad, it's a very minor complaint just that it didn't totally match the manufacturer picture as far as the background whiteness. It's still easy enough to read, even from across the room.
