100 percent humidity??

So today I bought a new hygrometer, hoping it would be more acurate then the one i had previously used. Now the hygrometer is reading 100 perecent humidity!! It is humid where I live, but I didnt think it was that humid. I moved him to the least humid room of the house, and there is a fan in the room running, but otherwise im not sure what to do. Id rather not have to buy a dehumidifier if i can find another solution, unless someone can link me to a cheap one i can get in canada!

yeah its kinda looking broken...

Those dial-type thermometers and hygrometers are notorious for giving false readings, even if they don't make it so obvious as your is doing. They tend to read low temperatures when it's really waaaay too hot, and higher humidity than the air actually has, which gets your husbandry all screwy, not really through any fault of yours. I'd pick up an Accurite digital thermometer/hygrometer from your local pet store, or some people suggest Walmart might have them. The internet is my best friend for finding things like that.

thanks ill be sure to invest in a digital one ! Do you think it would be possible for me to return this one..

Depends on the store policy of where you got it. If you still have your receipt and/or packaging, I'd try to take it back. Just calmly explain that it's not giving you any kind of accurate reading, it's clearly broken, and you'd like to get something else instead of replacing it with the same item.

We bought several digital ones from WalMart for around $8 a piece. Nice digital display and very accurate. Good luck!

I have never tested a good digital one that was reasonably priced. That does not look like a good analogue one either however. A good analogue one must have two features a metal face card (not paper) and a calibration screw. i don't know that brand at all but if it has a calibration screw in the back it is easy to correct http://cigars.about.com/od/humidors/qt/hygrometers.htm

Digitals are very fragile and if they get dust on the sensing part they should be checked and/or discarded and also most recommend new batteries every 6 months as ANY change in power will alter the readings or any change in resistance also (dirt dust ect.). the real killer is many brands list in the specs what is acceptable by the manufacturer up and down. many are 5%+/- but some are 10%+/- allowable and some worse than this. Accurite being on of the worst listed specs of any thermometer/ hygrometer I have seen (4ºF+/- and 15%RH +/-) I would not suggest buying a hygrometer that cannot be changes with an adjustment. most of the adjustable digital units are easily moved (by your snake) and costly the test kit (salt and electronics do not mix well) and batteries make it an unnecessary on going expense.

I bought the exact same ones not too long ago. Only one out of 4 was accurate. I do not recommend any of these. I now use acu-rite that I got from home depo for $10 a piece. They do require a battery and it is digital. It gives the ambient air temp and humidity level and I have not have had any issues out of them and I highly recommend them. I just keep them inside the enclosure on the top of the box hides.http://www.homedepot.com/p/AcuRite-D...0#.UdrKT53D-M8

Of the accurites I have had the best was 4ºF high and 9% low. I have yet to find an accurate accurite yet. I like ones that can be made correct easily rather than adding sticky notes on units. I never like batteries inside an enclosure! They can leak battery acid and acid gasses especially in warm humid places.

The question is which hygrometer is actually accurate? All the ones that was listed in the forums seems to not give an accurate %. I use to use these:http://www.amazon.com/Brass-Hygromet...ass+hygrometer but I learned that they were not very good. There has always been debate on which is more accurate but I still have yet to see one that is 100% correct.

Do a salt test to check the accuracy - http://www.youtube.com/watch?v=d7Ap96SlGZA

The ones at walmart are complete crap.

I own 14 brass ones they are all with in 1% of each other and can very easily be calibrated, I do so every 6 months. I have a bunch of digital ones that are all manufactures and run from 18% to 99% when placed in a 70% environment. they may start ok but quickly go off. Digitals that use a resistive sensor go off quickly and are very fragile they do not handle dirt or dust well. The accuracy in my experience of digitals is only good for 6-8 months then it is hopeless (beyond 10% off) I save a ton of cash with calibratable analogue. The digital units that can be adjusted are costly and the dial easily moved I have found the two I have to be fine in the evening and completely incorrect in the morning. I believe my snakes in exploring 'adjust' them.

I calibrate and check every unit every 6 months and it is rare for me to need to adjust more than 3-5% the digitals are all over the place and the test kits are expensive.

hm i never realized the fight to figure out the correct temperature was so hard haha

And just thing.... When you finally get it right for the summer, fall will change everything and the of course winter. I, for one, won't be bored anytime soon.

Thats the one good thing about where I live... We have two seasons: hot and cold.

That is funny so do we winter and summer with a couple days of fall and spring.

In my experience, hygrometers aren't great, and it's just something you have to make do with.

I've used some of the analog hygrometers (including the one kitedemon linked, purchased from the exact same place). I've never found one that was decent, and the calibration on them always slipped shortly after calibrating them.

There's lab grade hygrometers, but they're pretty expensive. I've never used one so I can't comment on them.

For myself I've settled on a cheap digital unit from the hardware store. Every time I've checked its accuracy against the humidity reported by the weather station, it's always been close enough, frequently enough, that I'm confident that my enlcosure is within the acceptable range, and so far I've seen no indications from the snake that it isn't.

At work we have a lab grade hygrometer they could never be used in an enclosure! They need very careful attention and care to be kept clean. There is no way it could ever be made to work. Unless you were ready to replace it often. ;) (700$ a unit)

Yup, that's even more expensive than the ones I was thinking of. Seen some analog ones claiming to be "lab grade" starting at ~$80 online. Still probably not well-suited for using in an enclosure though.

Ahhh I think those ones are often hair types they actually use hair as a movement. They are too fragile.

It is always a balance between durability and accuracy. The brass ones I have (the one I linked) are reasonable accuracy and exceptionally robust. I check mine ever 6 months and I have yet to have one more than 5% off. I don't know why you had so much problems with them I have a lot of them and never had any issues. I have a box of dead digital ones I have never had much luck with them.
