Digital hygrometer accuracy check

[GTS21]

Ok, here are the final readings:

Western III: 74%
Diamond Crowns: 68%, 69%, 74%, 77%, 77%

Not too horrible, but two of the Diamond Crowns are out of speck. They are suppossed to be "accurate to + or - 3 percentage points"

I'm now testing another another two Diamond Crowns and one Radio Shack wireless. I wonder if they'll let me return/replace the two Diamond Crown units?

I have 1 digital only for the wine cooler. I recently checked with a 69rh Boveda pack from a recent box purchase. I just sealed the digital inside two ziplock baggie with the Boveda. Was surprised was reading light by 4 two recent tests. Now I just add 4 to whatever it says. The feel test usually works for me also when all else fails.

I only have one digital that reads +7%

I rarely look at and calibrate it once a year. If I feel inclined to do so, I will move it to one of my 9 coolers, but don't use anything in my 3 desktops.

Don't obsess over numbers......

I wish they'd digital hygros that you could recalibrate. Mine is permanently offset by 10 degrees

Yes!!! How hard would it be to add the feature? Shit, I'd pay a good premium for this feature.

Some results on additional hygrometers (same testing methods as above):

Two Diamond Crowns: 76%, 76%
Radio Shack wireless: 74%

Not too shabby!

I compare my three hygro's on one box to check accuracy. As mentioned before, not too scientific. When ever I do this, they all three read within 1/2 degree in temp and all the exact humidity. They are all the Little Havana Perfecto type. I guess this shows that at least this manufacturer is precise about his calibration point. The only other thing I have to go on is that (until recent problems) my hygros read between 64%-67% in my humidors with Heartfelt's 65% beads. An accurate, inexpensive calibration kit would be useful.

Four Radio Shack wireless: 74%, 74%, 75%, 76%

Impressive showing for the Radio shack wireless units.

I know this is an old post, but I just salt tested the 2 Holmes digital hygrometers that I have and both are off 12-15% on the low side. I suspected that all along, but felt the urge to confirm it.
