Review on 🌡️ JEDEW 2-Pack Mini Hygrometer Thermometer: Ultimate Digital LCD Monitor for Indoor/Outdoor Humidity Meter, Temperature Control in Humidifiers, Dehumidifiers, Greenhouses, Reptile Habitats, Plants, and Humidors - Fahrenheit(℉) or Celsius(℃) by Rex Bareham

Someone may have gotten a bad batch but I had both calibrated equally and adjusted my Oasis IV Hygro fine tuned with the 75% Boveda package. I use Oasis in my traditional desktop cigar humidor and these little ones are in acrylic jars. Just remember that the sensor is on the bottom of the device. So putting it in your pocket with the sensor down will result in slow/false readings. Make sure there is breathing room at the bottom of the unit and you can read the airflow/relative humidity. I put my tape on the cigar pitcher and its right on the money for about 2 hours when I left it closed. flow slowly and need more momentum.
