Acu-Rite

[fender120993]

Hello,
I just today got the Acu-Rite thermometer and hygrometer
and the humidity that was read on the acurite said somewhre around 36...


My old dial hygrometer said about 51

Is it possible that the dial is that far off?
It is made by zoo-med



And does the fact that the dial is located in the top left corner (COOL SIDE) and the new acurite is located in the bottom right corner(warm side) affect the reason of this enourmous fluctuation.

===Thanks in advance===

Yes, it is very possible for the dial kind to be that off. Those things are crap.

Also, since BPs are ground snakes, everything used to measure temps and such should be near the floor to see what the measurements are where they spend their time.

Glad to know you got the good thermometer.

Not to step on toes here, but in my opinion the acu-rite thermometers and hygrometers are junk. I know a lot of people on here use them, but I don't trust them and here is why. I have 4 of them and if I set all the probes side by side and all the displays side by side I get temp differences of up to +/- 5 degrees. As for the hygrometer part I was getting differences up to 20%.

I didn't like this so I went out and paid some big bucks on some Iso-9000 certified calibrated gear that actually comes with a certification in the box that gaurantees the calibration. From my testing the Acu-rite Hygrometers do not work, differences of up to 40% compared to my calibrated piece of equipment. The dial type may be off but I can mark them with a 50% reference and 70% reference using my calibrated piece of equipment and know when my humidity is within that range, below that range, or above that range. As for temps I can sort of use the Acu-rite as a reference as I document the temp it reads when my calibrated piece of equipment reads good, then I remove the calibrated piece and know then temps go up or down. If it goes up or down more than a degree without being disturbed I get the gun out and start checking!

Well, I too have had some acurites go weird on me all of a sudden, but for the most part they are reliable. I think the main problem is when they get wet...so I don't spray near them anymore and haven't had one blink out yet.

But I also agree that having a temp gun is a must..just to make doubly sure.

ive had the exact thing happen with the humid, i put the acurite in the exact same place as my zoomed dial and the reading was off by 20%

so which one should i go by?
