Easy and inexpensive way to check and calibrate my home hygrometer. Too easy!

The idea is elegant! The magic potion inside the sealable envelope will maintain a stable humidity inside the envelope that your hygrometer must match.Leave it in there for a couple of hours (8, actually) and see what your hygrometer reads through the transparent bag. Then, take it out and turn it up or down, depending on how many clicks or turns it takes to match. Stick it back inside the back to make sure you got it right.I believe that—as long as the bag remains well sealed—the magic goop inside remains potent to maintain the set humidity. (But I used to believe in the tooth fairy as a kid too.)

The bag is small and my Hygrometer has been calibrated and this bag is now showing it off by 5 higher compare to using a ziplock bag with salt which is a guaranteed calibration. I have not talked to Boveda about this but considering what the Boveda pack does and releases in the air, this makes me consider that re-calibration is needed because of Atmosphere change of this product. Of course I bought this for testing and installing a Hygrometer in a cigar box. With the hygrometer sitting right over the pack this does not change the fact what the Boveda pack will do in the cigar box when the Meter is not right over it.With FBI terrorism rising and the FBI hacking accounts across America. My full review wasn’t posted and edited live while typing. I applied an update on certificates knowledge for the public after studying and chemistry test on Boveda products and it was edited out and for those missing it. It’s all over Fox News about Federal Terrorism by the FBI. And all the Government Terrorism the entire agency is guilty of. That’s if it’s not filtered out in your area.01/25/25 Update: I doubt this has anything to do with defectiveness of product but this test kit has the zip lock seal ripping off the bag where it seals shut after about 15 uses. The bag didn’t last the full cycle of the pack. That’s on Boveda, buyer beware.

Works perfect... it's probably your hygrometer (+/-)!

I bought a pack of like two dozen of the humidity/temperature sensors on Amazon and they varied quite a bit from one to the other which is not good when you trying to regulate humidity for cannabis plants. I bought one of these Boveda calibrated packs and was able to put the percent humidity correction on all of the sensors that I bought using a small piece of freezer tape

It's very easy to use. Just place your hygrometer in the bag, seal it. 24 hours later, your hygrometer is calibrated. Put it back to work in your humidor. Don't toss the bag away! It's good for 3 months!! Inexpensive fix!!

Di sicuro il miglior modo per tarare con estrema precisione il proprio igrometro. Sono rimasto molto soddisfatto! Consiglio l'acquisto a tutti coloro che vogliono incollare la proprio lancetta al 75%.

I'm in the process of designing a product that measures the temperature and humidity of beehives. There are plenty of temperature sensors on the market that are cheap and accurate, but humidity sensors are generally pretty expensive in comparison and, as I've discovered, wildly inaccurate.Having purchased a sensor that I had some confidence in, I needed to test it. I created my own testbed, with very accurate control of temperature, but I needed a way to accurately define a level of humidity.There are a plethora of YouTube vids on the subject demonstrating how this can be achieved using a home-made salt solution in a bottle cap, but even having purchased some lab-grade sodium chloride and distilled water my results were all over the place. It was while I was doing more research along these lines when I can across some adverts for Boveda products in relation to maintaining the humidity in humidors, a cupboard for cigars.Looking at the Boveda website I discovered that they produce larger product packs for cigars, but also produce smaller packs with high tolerance chemical solutions that can be used for hygrometer (an instrument used for measuring the amount of humidity and water vapour in the atmosphere) calibration and purchased a pack.The Boveda One-Step Hygrometer Calibration Kit allows a high degree of reliability, with a high degree of accuracy simply by placing the hygrometer, or in my case the sensor, in a small airtight container. The kit comes complete with an air-tight plastic bag and the Boveda humidity pack. To use it, you just put the device to be tested in the bad and let the humidity in the bag settle for 12 hours or so, it's as simple as that.In my case, I placed the sensor in a small bag, sealed the bag around the wires from the sensor and placed the whole pack into my chiller. At a consistent 21.5 DegC (+/- 0.3 DegC), I let the sensor soak for a day and then analysed the results.Long story short then, the results where excellent. Incredibly stable humidity results, at exactly the level I was expecting, well within the tolerances stated by Bovida and the sensor I was calibrating during my experiments. I certainly won't be mucking about with salt solutions any more.My only regret is that I've spent a fair amount of money of lab-grade chemicals and that my better half is getting peeved with the 1Kg of salt that's taking up cupboard space. Still, I guess I can use it on my fish & chips?

I calibrated all my hygrometers with this, most importantly the digital one.Worked perfectly.
