Hello,
I am trying to reliably measure the humidity in my basement. I currently have three hygrometers in use, but they show significant differences in their readings. For testing, I have placed all three devices side by side.
Here are the indoor readings:
1 (one that measures with an external sensor, but also shows indoor values on the device itself, manufacturer TFA Dostmann):
19.9°C (67.8°F) temperature, 70% humidity
2 (one that I can also access via an app and Wi-Fi, measures directly on the device, manufacturer HapopFan):
20.1°C (68.2°F) temperature, 63% humidity
3 (a very cheap one sold in sets of three for about 10 euros, measures directly on the device, very popular, manufacturer Thlevel):
20.0°C (68.0°F) temperature, 55% humidity
Do you have any idea which device might be the most reliable overall? Of course, you can’t tell for sure just based on these numbers, but I am open to buying a new one if necessary, as long as I get a dependable reading.
Regards

However, the devices from the company Thlevel also generally receive good reviews. Compared to TFA, there is about an 8% difference.

MarCologne25 Oct 2024 18:14I tried the damp towel method with all three of them. After 30 minutes, numbers 1) and 2) were both at 89%, and 3) was at 81%. Now, two hours later, they have all returned to their original levels. Very strange.
