Boveda Calibration Kit

even easier than a salt test

Worked great

Worked great but the bag was not quite clear enough to read the hygrometer without opening and releasing the humidity. Made the entire process a bit of a pain. In the end I used a Ziploc baggie and made it work.

Works great for my humidistats

Seems to work well. Really no way of confirming if it has worked

Easiest way to calibrate, or just to check a hydrometer. Both my analog and Boveda Butler calibrations are hassel free with results I can't argue with. A simple test, just pop in the meter(s), wait prescribed time, & you're done! Eazy fix!

Easy to use......

This worked perfectly. Needed to calibrate my sensor and with the 24 hours it was reading correctly.

Simple and inexpensive way to calibrate hygrometer. I’ve purchased several different brands of hygrometers and readings have been all over the place. This product enables you to effectively determine/manage their effectiveness and adjust accordingly.

Very easy calibration of my CI sensor for my humidor. Pop sensor in bag and wait 24 hours. Sensor should read 75 %. If not make adjustments when reading sensor + or -. Easy.

Works as advertised. I was able to calibrate 3 or 4 hygrometers without issue.

This worked well to calibrate a handful of small hygrometers, it fit 4 or 5 of them in one go without feeling like it would burst or rip apart. The front could be a little more clear as it is more translucent than clear. It is easy to see what is in there but not easy or even possible most times to read through.

Quick, easy and accurate

Great for starting brand new humidor

Works perfectly to calibrate my humidor’s hygrometer. Large enough to put multiple hygrometers in . Very happy with this product.

This is perfect way to calibrate your hygrometer

Calibrated my hygrometer in the kit. Worked well !

Worked as advertised. Simple.

Boveda 75% Calibration Kit is a sure fire way to check your hygrometer's efficiency. The salt test is also a good way to check humidity - If !! you have the proper mixture of water and salt. Too Thick - Too Soupy - could give different reading's of your hygrometers humidity. BOVEDA is the way to go. Accurate every time !!

Worked well. Used in ziplock to revive some old cigars afterward.

Works perfectly. Used it on two different hygrometers with identical results.

Always works great to know exactly what your hydrometer is reading. Have used for years.

worked as advertised

I saw great reviews for this product, and I’m sure it was great for everyone else. However, it didn’t work as it should have for me. I will try again with my new hygrometer and see if it works the way it should.

This is awesome. I will be ordering Boveda to provide the proper humidity control for my humidor

Does exactly what it’s suppose to do but I will admit you could just use a pack and ziplock bag to do the same.

Great product, work as described. Did 3 hygrometers, perfect!!

It worked as it should.

Has made calibrating all of my humidors so easy!

These kits can be useful, but sometimes I question the 75% humidity pack they put in. I’ve use these kits before, but the last one I had felt like something was a little off about it. So I put in a hygrometer that I knew was already perfectly calibrated and it wouldn’t go any higher than 71% following the directions of this kit. With that said, buyer beware that there is a chance this kit may not help you perfectly calibrate your hygrometer. There’s probably about as much room for error here as there is with the salt and bottle cap method. Better option would be to get the 32% kit (I don’t know if CI sells them or not). Use the salt/bottle cap method for your high (75%) test, and the 32% kit for your low test. This is probably the best way to try to keep your hygrometer as accurate as possible for the cheapest price.

Works as intended. Great product!

Very easy to use! I’d recommend to test your hygrometer. I was able to test my hygrometer and calibrate it.

Made life real easy calibrating my hygrometers

Tells where your gage calibration is at.

Used product with Oasis Caliber IV for calibration check. The bag says 24 hours but the humidity didn't seem to hold when moved slightly. 48 hours is a better time span to ensure proper humidity held in the bag. The bag doesn't mention the common sense put in a dark place away from sun as you would your humidor if you are having issues. Had to reset calibration on hygrometer -4% to hold steady at 75%

The humidity packages was great. I only have a problem with taking off from work to sign for non tobacco products.

Got the job done. Smokes are much improved. A must have for all setups.

Stupid easy my wife was able to do it!

Easy to use. Humidor didn’t reach 75 however It may have been the calibration was off

quick and easy calibration... well worth the effort to keep those stogies at the correct %

The Boveda 1-Step calibrator is so easy to use for the initial calibration and for the later tweaking and validation. Just ensure the packet is properly sealed after insertion and removal of the hygrometer and it will work exactly as touted.

Easy way to calibrate your hygrometer

It worked perfectly.

The size of the pack was too small to calibrate two hygrometers

Seems logical,put devices into controlled environment and make adjustments to correct calibration or know how high or low your readings are, gives a good base to start with, it all becomes a guessing game in the end but helpful.

This is the second one that I have gotten just Because they t was about 9 months and I was worried about the accuracy. It did exactly what t was supposed to do and I can now tell the accuracy of the humidity in my humidor.

This system was so much easier then the salt/distilled water method. With a collection of over 2500 cigars and various humidors I was able to calibrate all 4 Hygrometers in a short time with the precision I want.

Easiest most carefree way I’ve seen yet to get your humidor set

It works just like it says.

Accurate and easy to use.
