This XIKAR humidor upgrade kit is the most reliable humidification system available today, and includes everything your humidor needs for an optimal "cigar fresh" environment.

Digital Round Hygrometer
XIKAR PuroTemp Hygrometers have been redesigned to ensure accuracy right out of the box, without having to calibrate. XIKAR hygrometers are manufactured to exact specifications for long term accuracy and minimal maintenance. They accurately display the relative humidity and temperature in your humidor. !This hygrometer is not user calibratable!

250ct Crystal Humidifier
XIKAR humidifiers are prefilled with PG Solution and will emit and absorb moisture in your humidor. XIKAR humidifiers with PG solution maintain a 70% RH (Relative Humidity). Varying humidity levels in a humidor can destroy cigars quickly. Proper humidification accessories will ensure consistency, which is the most important step in preserving and protecting your cigar investment. (The humidifier contains some "starter" PG solution so that it is ready to use and get you started. It is not filled to capacity.)

8oz PG Solution
XIKAR's Propylene Glycol (PG Solution) maintains 70% RH. Use XIKAR PG Solution every time your crystal humidifier needs fluid, not distilled water. Distilled water evaporates quickly and creates humidification fluctuations. XIKAR's proprietary mix of PG Solution is calculated to match the water absorption rate with the rate at which PG biodegrades, resulting in a humidor that will not over saturate with PG. Maintain 70% RH for a "humidor fresh" smoke. Competitive mixtures of PG Solution often contain an incorrect mix resulting in a clogged humidifier.

Please note! 
For the humidification system to work properly, use XIKAR brand PG Solution. Other solutions may damage your humidifier.

For different temperatures and extended storage, it may be advisable to recharge the humidification unit as needed, but this will depend on number of cigars, humidity, temperature and cigar freshness.
