Thlevel Digital Temperature Humiditymeter Thermometer for House Mini Digital Hygrometer and Humidity Gauge for Greenhouse Cars Home Office Black 6 Pack Square

Good accurate hygrometer. Perfect for a humidor.

They are small, very small, but great for the price. Just don't expect it to be accurate .... all 3 next to each other shows slightly different. My branded dehumidifier shows significantly different humidity level, sometimes ~10-20%.But great to give an indication about humidity level.After taking shower - shows 99% humidity :)))))

These temperature / hygrometer units came ready to use with batteries, there are no buttons, switches or any settings to configure. The display shows the current humidity and temperature reading in degrees Celsius and updates the readout roughly every 10 seconds.The units are very compact, about the size of a 9V battery. They appear to be designed to slot into something, like a cabinet or container to monitor the interior temperature / humidity, however they sit fine on their own standing up. I placed these in different rooms, each on top of a door frame as shown. They will also sit neatly along the edge of a shelf.Although the display does not light up, they are clearly readable even in low light, particularly the large humidity reading digits. The readings appear to be accurate with the 6 pack I received all being within 1 to 2% of each other for the humidity and within 0.5C for the temperature as shown.The only feature I wish they had is a Min / Max reading like some other hygrometers, but for the price they are great value for monitoring the humidity around the house, such as to see how well a centrally positioned dehumidifier is at tackling the humidity in each room.

Excellent 👍

They are small and good to put where you need them but got different results to other devices and not sure this its the correct figure

They arrived already on, there’s nothing to do except fit. I checked all 6 in the same surroundings for 2 days to see what the variance was. About 3% on RH over the 6 and less than 1C over the 6. To be used in Mantis enclosures, all fitted with double sided tape (not supplied) and working well. They are inexpensive so not sure how long they will last. The reading angle affects the clarity of the display but not too much of an issue.

They're pretty dinky, smaller than I expected anyway. Think half a matchbox size. Placed them all together in one room and got different readings on all three, in total were about 1.4 degrees C out from each other. Humidity seems accurate as it shoots up when the dryer is on, and down once the back door is open. Hard to read unless you're looking face on to them, any angle and you just see all the lines.Does it job to some degree, albeit accuracy isn't 100%, but can't expect perfection for the price.

Not an essential, but gives interesting information on what's going on in your home, I might have to get a dehumidifier in the kitchen by the look of things (86%!)
