My infused cigar humi needed some modding. I had this hygrometer from my humi, which was replaced by a hygroset. I threw the analog hygrometer in my calibration kit once I was done with the hygroset and came to find it was only -1 off! I figured this would make a great addition to the jar! lol
Steps:
1: Grab old crappy hygrometer
2: Clean all surfaces
3: Use a thin bead of clear silicone caulk around the edges of the hygrometer
4: Stick it to the center of the lid and let it cure for 24 hours
5: (Optional) If you dont like placement or stops working, peel off, wipe clean, repeat step 1.
