Review on 🌡️ Searching for Accurate Temperature and Humidity Readings? Get the Rojuna 5-Pack Mini Thermometer Hygrometer with LCD Display! by Alex Britton

Works well. They were all about 5/6 points lower (low). Not bad for the price. You can't calibrate them, but you can check their accuracy and use +/- to adjust them. I used a lid full of salt with a few drops of water sealed in a ziplock bag. They should have shown 75% but they were 4-6 points down. I just added 5 points to everything either of you read and it will be within 1 +/-%. . That's enough for my cigar humidor. If you want or need higher accuracy, spend $$$ and get one that you can calibrate.
