Caliber IV - Digital Hygrometer Thermometer

My first two purchases were the Xikar Hygrometer Rectangular version. On both of these Xikar hygrometers the tolerance is 2% either way whereas the Caliber IV is 1%. Both Xikars were not within specification using the Boveda Hygrometer Test kit. Bought a Caliber and popped it into the bag and within 24 hours it is reading bang on 75%, as it should. Both Xikars are being returned for the Caliber IV. Fantastic hygrometer with easy to read Relative Humidity (RH) and Temperature and on top of that you can alter the device if it does start to drift. Please don't make the same mistake I did. Go for one of these. You won't be disappointed!

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.

Awesome bit of kit! This is extremely reliable! My friend has 1 of these too so we did a test to see how accurate they are within each other. We expected a plus or minus but to our surprise they both read the same humity level in 2 different humidors....i need say no more.

A very common question answered, Do I remove my box of 25 tubed cigars from their tubes before putting them in my humidor, the answer is YES, so what's the reasoning behind this definite answer, Tobacco is an Hygroscopic material which has the ability to absorb or release moisture depending on it's local environment if the environment is humid the cigar will absorb moisture until it equalizes with the environment if the environment is dry the cigar will release moisture, so that's the science lesson finished, the next variable is quality control in an ideal world all tubed cigars would contain the ideal moisture level and the sealed tube would maintain this but we don't live in an ideal world so you have the possibility of tubed cigars even out of the same box being under humidified, ideal or over humidified, so basically you take pot luck as to the condition of your tubed cigars, so what do i do to get consistency, put the untubed cigars in a correctly set up humidor around 68 RH and around 18c temperature, from the science lesson the under humidified cigars will take on moisture and the over humidified cigars will release moisture allowing several weeks for this to happen, only open your humidor once a week to remove a weeks supply of cigars which you would keep in their original tubes. KEEP THE CIGAR OILS AND TASTE IN THE CIGARS IN THE HUMIDOR, THESE AROMATIC OILS CANNOT BE REPLACED.
