Experts suggest that you re-calibrate a hygrometer every 6 months, but for my application I’ll probably only do it every year or two.So how did my little $25 hygrometer do? | Steve Jenkins is an Internet entrepreneur, tech CEO, all-around geek, speaker, consultant, martial arts black belt, PADI rescue diver, obstacle course racer, and self-proclaimed technology Jedi and business samurai who is passionate about anything that has blinking lights, a throttle, a trigger, or a Swiss movement. Place 1/2 cup of salt in the coffee cup and add the water. Always give a hygrometer about two hours to stabilize before taking a reading, as changes in the relative humidity may take a while to register accurately on a hygrometer. It is best to read it while still in the bag. I didn't know if I put enough salt, too much water, etc. Don't add so much water that the salt dissolves; you just want it to be wet. What the hell is going on?! Place 1/2 cup of salt in the coffee cup and add the water. To test this claim, I resorted to the tried and true “salt test.” It’s simple, accurate, and inexpensive.
Put the cap and the hygrometer inside the baggie. 5. Give a hygrometer about two hours to stabilize before taking a reading, as changes in the relative humidity may take a while to register accurately on a hygrometer. You need a paste – do not make it thinner than this. Place a zip lock bag flat on a flat surface. Wait 5-6 hours and check the value on your hygrometer. Dampen the salt with a few drops of water, and put it along with your hygrometer into a tightly sealed tupperware container. Well once you waited the 8 hours, your hygrometer should read 75%.If they don’t, then you will know exactly how far off the calibration truly is! Some dial types will have a small screw or adjustment on the back so you can adjust them after calibration. Add enough water to make the salt wet, but not so much that the water stands on top of the salt. You can opt-out at any time. Now you can make the necessary adjustments to your hygrometer (read your instruction manual) to ensure that your humidor is reaching and staying at your desired levels.Fill in your details below or click an icon to log in:Don't miss out on any of my post....Enter your email address to follow this blog and receive notifications of new posts by email. A simple method of calibrating your hygrometer will help ensure you are measuring the relative humidity as accurately as possible. Stir for a bit to totally saturate the salt (the salt won't dissolve, it will be more like really wet sand).
I usually use my finger for this by dipping my finger in the water and letting the droplets fall off the tip of my finger and into the salt.What you are looking to create is a slush like consistency, you don’t want to have any standing water on top of the salt. Well once you waited the 8 hours, your hygrometer should read 75%.If they don’t, then you will know exactly how far off the calibration truly is! You can pour off excess water if you put too much in, or play with the water/salt mixture to get it right. Sit this bag aside at room temperature for eight to 12 hours in a location where the temperature is fairly constant. STEP 2: Add tap water to the bottle cap to saturate the salt. All you need is:The science behind this test is that a wet sodium chloride (table salt) mixture will establish a relative humidity in an enclosed space of precisely 75%. For more details, see our The cup with salt and water is placed in a bag (the hygromter should then be carefully placed in the bag, then the bag is sealed). Water; Fill the cap with salt and add enough water to make a thick slurry. It is a beautiful Friday night. Once you have made the paste, place both the hygrometer (turned on if digital) and the salt solution into the airtight container and close the lid or … It can be measured as absolute humidity (the amount of water vapor in a unit volume of air), or a relative humidity (the ratio of moisture in the atmosphere to the maximum moisture the atmosphere can hold). Here’s how you do it:You can actually use this method to calibrate multiple hygrometers at once (as many as you can fit in the bag). How to Calibrate your Hygrometer “Salt Test” It is a beautiful Friday night. You instantly look at your hygrometer and it reads a perfect 70%! Do not put so much in that the salt gets "sloppy".
Lianne is a veterinarian, epidemiologist, and freelance writer who's written nearly 400 articles for The Spruce Pets. Don't add so much water that the salt dissolves; you just want it to be wet. If it reads below 75 percent, you will need to add the difference to your actual readings. Boveda has those calibrating packs that you should use instead. Units can be calibrated using the salt test method. Make sure you do not add too much water where the salt dissolves or turns into a liquid solution. Fill the cap with salt and add enough water to make a thick slurry.
The temperature should be fairly constant. “It’s not the heat… it’s the humidity that gets you.” Not only is that true for personal comfort, but even more so for important items that need to be kept at a specific humidity (like cigars at 70%) or metal parts on guns (which want to be stored in a dry location). You walk over, crack open your humidor, pick up a stick and damn it… your cigars are completely dried out. Pick a location free of drafts, out of direct sunlight and away from heating or cooling vents. The last page in the series provides a summary of the steps that you can print out for reference.
If yours is not adjustable (like mine), simply make a note of how "off" your hygrometer reads. Next, place the cap and your hygrometer inside a zip lock bag or a plastic container and seal it. Place the sealed bag aside at room temperature for eight to 12 hours.
Well, when you do this test, the paste in the cap reacts with the air to create an environment that is exactly 75% relative humidity. Sorry, your blog cannot share posts by email. You decide this is the perfect time to sit out on the back porch, drink a glass of your favorite Scotch, and enjoy one or maybe two of your premium cigars that you have had resting in new humidor you got last month. It seems like a lot.
