Ensure your tobacco, herbs, and smokable products are stored and cured to perfection at a glance with these hygrometer lids designed to fit any wide or regular mouth mason jar with standard lid sizes of 3-3/8" and 2-3/4" respectively. Simply replace the metal lid that came with your mason jar with one of these lids and insert the appropriate hygrometer in the hole provided. The underside of the lid features a retention ring designed to help keep the lid centered on the jar while tightening the metal ring that came with the jar when you purchased it. As with any humidor style product, in order to maintain the humidity inside the jar, use a humidity pack designed to maintain a consistent humidity from manufacturers like Boveda or Integra Boost. For best results, and to ensure the longest life of your humidity pack, at your discretion you may glue the hygrometer in place with a rubber cement or other glue that remains flexible after it cures/dries. These lids come as a set of 4, are available with round or rectangular holes, and can be purchased with or without the hygrometers. *Note: These hygrometers display the temperature in Fahrenheit. They are consumer grade and as such, have an accuracy of approximately +/- 10%. Please expect some variance between units. Colors for lids and hygrometers may vary. Lids with hygrometers are shipped unassembled, and without glue. Hygrometer batteries can be removed or flipped upside down in battery compartment to save the battery when not in use. Hygrometers are non adjustable and will require calibration against a known humidity, and subsequent recording of the percent deviation to provide an accurate calculable humidity. 3D printed lids are not dishwasher safe. Hand wash in lukewarm water only.
