RH vs humidity level gauge from cigar humidor

[KarlJay]

I bought a Csonka humidor accessory kit. I needed a small humidity gauge and this kit had one. It's called a "Radial Hygrometer Humidity Gauge"

I wanted to test it so I put it in the freezer along with my digital RH gauge.

An hour later, the digital says 16% and 18 deg F ... the Csonka says 50%

Before I started the test, they were both at about 40%

I got this to put inside the jars because it's about the size of a quarter.

Is this normal, is my test valid?

Should I put them in the same sealed jar and add a spray water to run a few tests?

Is this the difference between RH and Humidity?

I expected it to be accurate because it came from a smoke shop and seems to be a "brand name"

humidity is humidity. I would do the bag trick salt salt and water in a bottle cap and sit the hygrometer in the bag with it and wait over night. I usually just leave the top off my jars threw the night and leave them on during the day. My last harvest I left he tops off until the buds were completely dry then leave the top on for the rest of the cure. That way it ensures that the 62% humidity will set in for sure and stay there.

Inside the fridge and freezer, they came up with very different numbers...

So, I put them inside a sealed glass jar and they came out equal! Strange.

I put them both in a jar in a warmer room, could be then need to be in the jar. If so, no problem it is for use inside a jar.

That's what it seems like.

Inside the jar at grow room temp they the cigar one was 10 higher, 50 vs 60.

I don't think this thing is going to be of any value. I'll try another smoke shop and see what they have. Shouldn't be that hard to get something that actually works.

I bought my hygrometers from fleabay cheap digital

I'm doing the salt water test right now, it's been a few hours and it looks like it is VERY close. It says 71/72 and it's supposed to reach 75 at 4 hours...

I'll check the digital one next.

Nice simple test, never heard of the salt water test before.

Thanks Wiz for the heads up!

No problem

The Cigar gauge tested so close, I've got to call it right! so it's in the curing jar and we'll see what it reads. I put the digital one in the bag and I'll see where it reads after a while. It's a common cheap one so who knows. I'll test the 3rd one after that.

 

[KarlJay]

More than an hour in and the digital one is reading 56%... That's the one I was trusting :O Maybe this explains the difference between the digital and the other cheap one I was using before I got the cigar one.

I'll be checking the cheap radial one next.

The sad thing is that the digital one give me the high/low readings and I liked that.

Its going to be hard to get tehm all to read equally. Most hygrometers has dials on them to adjust

After I read this, I went over to see if the cheap radial one had an adjustment. Looked on the back and it does! Glad you posted that.

Now I don't have a clue what to do with the digital one, maybe it has some kinda adjustment screw.

I should probably take back the made in China digital one. POS cost me more than all the others and it's trash.

I would stick with the digital
