AcuRite Hygrometer and The Beginner Guide To Hatching/Incubating

[kelltang93]

You do not need a thermometer or a humidity gauge That is specifically made for an incubator.

I'm not exactly sure which model you are talking about... Can you please post a direct link to it or take a picture of it?

I use this:
AcuRite 00325 Indoor Thermometer & Hygrometer with Humidity Gauge, Black, 0.3 https://www.amazon.com/dp/B004K8RF1...t_i_14MGX3R9HNFDP3M9BE6N?_encoding=UTF8&psc=1View attachment 2983575

That's the one I bought, great now. I can return the other one, thank you, you were a big help.

Do the salt test to make sure it's reading correctly.

Put a little bit of salt in a container and mix some water into it to make it a thick slush.
Put the container into a Ziploc bag.
Put the accurate into the Ziploc bag next to the container and zip it tight.

Leave it overnight.
After leaving it sit in the bag overnight it should read 75%.

If it is reading 80% you will know that it is 5% off.
5% too high.

Thanks, but can you calibrate the Acurite hygrometer?

You can salt test it to know if it is reading correctly or not.

You can salt test it to know if it is reading correctly or not.

Yes, then just write down any deviation to figure into the readings as you take them during incubation.

I tried to do the salt test like the video by putting a tablespoon and a teaspoon of salt and it didn't come out like the one in the video. Any help?

Hehe. That is a ton of salt.

A) Put 1 tablespoon of regular table salt (sodium chloride) into a small dish or container and add 1 teaspoon of water. Stir to totally saturate the salt. It won't fully dissolve but it will look like a slushy. Don't use "lite salt" or "no salt". You want 100% sodium chloride but if it contains iodine, that will probably work fine since it is a small concentration.

B) Place the dish into a resealable quart or gallon ziplock bag along with the hygrometer and seal the bag. Puff up the bag a little. Don't let the salt mix come in direct contact with the hygrometer.

C) Set the bag in a location where the temperature is fairly constant at room temp out of direct sunlight. After 8-12 hours check the reading of the hygrometer while still in the bag. It should read 75% relative humidity. If it does not, then you know how much the reading is off.

D) If your hygrometer reads 70%, then the math is:
75 (should read) / 70 (your reading) = 1.07

Now when you look at the hygrometer reading, multiply what you see by 1.07 to get the real humidity.

Why should it read 1.07
