Caliber IV - Digital Hygrometer Thermometer

Date Added: Monday 04 November, 2013 by Jason

Bought one of these to act as a secondary back up to my main electric Humidifier. After doing a 24 hour one step test this unit was 100% spot on. So when I placed it inside my Humidor I was shocked when it showed me my humidifier was out by 8%. Unlike my Humidifier this unit is still inside my humidor giving me piece of mind that the % levels are correct.
