Which of these temp/humidity readers would you trust more?

Are the temp guns more accurate??

I just wonder now about the accuracy of the Acurite I have....Maybe I should get a heat gun too...



@Serpent Merchant: what is the "Salt Test"??

No they aren't, at least not the cheap ones used in the hobby. Most are actually worse.

Salt Test: http://www.cigarpass.com/cigars-101/...ygrometer.html

so you would or wouldn't recommend one??

I currently just go off my accurite probe for judging the hot spot, and assumed that the reason acurite was so widely used was due to the accuracy of its measurements...

I forgot the part in Chemistry about accuracy vs. precision :p

Temp guns are a great tool, don't get me wrong. I have one and use it all the time, but people need to realize that they aren't any more accurate than most decent digital thermometers. Most are at least +/- 4 F, that is about the same as an acu-rite. The really cheap temp guns can be even worse.

I would recommend temp guns mainly to people who use rack systems, that is really what they are best for. $ for $ temp guns just don't make a huge amount of sense unless you have a very large collection. Why pay $125 for a temperature measuring device that isn't any more accurate than a $12 unit? Why pay $40 or $50 for one that is worse than the $12 unit?

The cheap temp gun I got at Lowes a few years ago is always within 1 or 2 degrees of what my Herpstats are set to. I've had several Accurites and they're all over the place...i.e...+/- 10-20 degrees...

I'm not sure what temp guns you use but the one that I use is within a degree of my herpstat reading. It's was also within a degree of my vivarium electronics thermostat.

You can look up the datasheets yourself. I have a PDF of one somewhere I will try to find a post.

Just because yours read true doesn't mean they are accurate. When the manufacturer lists an error of +/- 4 F they do so because they know the limitations of the components used. The point of a toll wrench is that it is a range. Sure it can read spot on, but another day/another temp gun of the same model could be + 4 F. Some of my Acu-Rites read true, others not so much. The facts of the matter is that you are getting something rated for the same tollerence. A temp gun $50+ is going to be better, but is it 5x better?

Here is the data sheet:

These are nearly $100 temp guns from a good brand, and they are only rated for +/- 3 F

So how can I make sure my Acurite is actually readi the right temperature??

You need something to compare it to. Something like a herpstat probe that is rated to be accurate. I know some people recommend buying 3-4 acurites and then averaging their readings. That is a bit extreme, but would work.
