There are instances when it may show 3 percentage points below or above the normal reading, 78% or 72%. To calibrate the hygrometer using the Boveda kit: 1. Therefore, you may need to quickly check it to see if it’s not the device that’s at fault.Should you take this approach, it’s important that you use a brand new Boveda pack to avoid any possible anomalies. not 100% satisfied with Boveda, return it for a full refund. 3. Upgrading to a digital hygrometer is not an option but they are unsure if their analog hygrometer really does its work.

If you have no idea where this calibration button is located, ensure that you check the exact location by reading the user’s manual.In case the device doesn’t specify a calibration button, you can look for the reset button instead. As long as your hygrometer allows you to adjust it to 69 if it's off, yes, you can use a 69 boveda. Analog or digital hygrometers can be used to measure humidity levels inside of If there is no screw (or dial) to recalibrate your hygrometer, then you will just have to remember to add or subtract the difference between the test reading and 75%, in order to determine the actual humidity level inside of your humidor. Using the Boveda One-Step Hygrometer Calibration Kit: Simply place your hygrometer inside the bag and completely re-close the zipper. For best accuracy, you want to calibrate your hygrometer with a reference that is close to the readings that you expect, so in most cases I'm thinking 65% would be closer to most people's target range than 75%.

For example, if your hygrometer test reading was 80%, then subtract 5% from the readings you get inside of your humidor, to determine the actual levels of humidity (e.g. Just press on this reset button at the soonest time possible to guarantee that the normal reading will return to 75%.Everyone’s been there.

Do-it-yourself calibration methods, like bottle cap salt tests are imprecise and inaccurate. You can seal in the plastic bag once you are finished with all preparations.To be sure that the hygrometer is correctly reading humidity in the plastic bag, you have to leave this for about 8 to 12 hours. So if you have that kind of hygrometer, you obviously couldn't use a 69 to calibrate it. One of those principles is that a saturated solution of salt in water will maintain a constant level of relative humidity inside an enclosed chamber. This is especially the case if you want to do a two-step calibration as described above.Meanwhile, a salt test consists of the following steps:Again, try to opt for the smallest container possible and ensure that it has an air-tight seal. Similarly, using different amounts of water may also give you different results.Finally, there’s no guarantee how well the humidity will distributed in the container. Put the hygrometer inside the bag but don’t allow this to touch the mix in the cup since this can end up damaging the device.You can ensure that it doesn’t happen by looking for a place where children or other external forces will not disturb the setup.You also have to place the setup in a place that has constant room temperature.
