That's great.

Odd, it was off by 4%, now it's off by 7% on a second salt test.

I just posted the results of a 48 hr salt test on another thread. Basically it was at 73% after 48hrs. I woke up this morning and it was at 74% (total ~60hrs salt test).

Nice review!
I am going to have to pick one of these up next time I'm out at Wal-mart. For the price, it seems to be a pretty good deal!

I have tested 11 of these to get to 4-5 of them that are 75% spot on via the Boveda packet test

Walmart just loves me returning them

How are you returning yours? Obviously they are open... so what are you saying? Just curious as I have one that's 4% off but goes up and down in the salt test so not so sure it's a quality one.

I like it overall and am thinking about buying another one, but I'm very hesitant due to my experience with my first one...

I have had great luck with the Acu-Rite and also own several Springfield from Wal-Mart, they are very small and just as accurate (+_ 2%) check with a known % you trust. They are the small white units with "PRECISETEMP" under the SPRINGFIELD label on unit.
Hope this helps, these work well, I have had to exchange two, but Wal-Mart is great about it, with or without receipt.

The one I have works well also.

I have two springfield's (smaller ones) and the AccuRite in the OP.

AccuRite - Dead on

Springfield 1 - Dead on

Springfield 2 - -2%


For the ease of use and size, I'd have to go with the Springfield. It is very small, compared to the AccuRite, and for the money, you can't beat it.

In addition, it's important to re-calibrate the hygrometers. Upon the first salt test, my Springfield 2 was -5%. Then, on a more recent test, it changed to -2%. So, there is some give/leeway in the numbers.

For the money, you can't beat these bad boys.


Caution - If you plan on using a neodymium magnet to fasten these to your humi, DON'T!!! I tried using a more powerful magnet, and right as I attached the magnet, the reading jumped several % points. It eventually bounced back, but I'm sure it's not good for the unit.
