Digital, Is it REALLY better?

Ok before everybody tells me what a dumb*** I am, I am not advocating for or against. I currently own 11 digital and 1 analog hygrometers (mostly xikar) and I know that most people completely rely on them, so do I. I use one of the Boveda Kit's to calibrate. The analog I have was factory equip when the Humi was purchased in 98 I didn't have a clue did not even know what humidity I was supposed to maintain and quickly gave up. Nine months ago I was reintroduced to the Leaf properly and my journey began. I dusted off the old Humi, acquired a new one and shortly after was given another one both with digital, the old analog was 1% off. Three months ago I re-calibrated and found variations from 1% to 3% off with all the digitalis, the analog is still 1% off. I have read several post that seem to suggest that it is somewhat common for the digitalis to be off this much or more after a similar time frame. I know they can be reset. My analog cannot the only thing I have done was to abuse it, It has survived a couple of very rough moves and still is only 1% off after 15 years. So is digital Really Better? I know there are people on here who have been at this a long time, What do you think?
That in and of itself create resistance and inaccuracies.
These two different metals work against each other when the "humidity" or dew point changes.
Now imagine this! So do the meat thermometers ! Your outdoor analog thermometers also !
So the coil relaxes or contracts and moves the needle as the "humidity" changes. Very inaccurate. Up to to +/-20%. This can vary from manufacturer to manufacturer.
Even the "hi accuracy" bi mets I sell are no better than +/-3%.
. Now take the digital, or should I say most digital.
They take into account heat and dew point.
Run an algorithm and WA LA !
You have a meter that is around +/-1%.
Makes perfect sense since the Analog is not temperature compensated.
Now let's take a look at my Monolith. The built in says 73%. The Caliber on the top shelf says 69%. The Caliber on the bottom shelf says 85%. I switched the calibers and same thing happened. So, I can conclude that there is much more humid air at the bottom since it is a bigger cabinet. What I don't get is why the built in and top shelf one are that different. Sometimes it will even say 84-85% and the top says 69%. So, I open the door and let some of the humidity out while I have a de-humi running in the house. Also, I keep my temps colder to offset issues with beetles. Anything that I haven't frozen that is in that humi has been stored at 41F for extended periods of time including about 2 weeks and then gradually brought up in temp to the 62F I keep it at now.
Swivel so 65 is at the top. Throw open the door. Pointing straight up? Okay, good to go, shut the door. Whereas the digital, I gotta squint at it to make out black numbers on a grey background. Got a digi in there to check it against now and then. Got a screw on the back to adjust it.
We tend to find elaborate solutions to non problems.
Curt...you geek!!! Thanks for the information! I use both (mostly because humis come with the analog generally) and calibrate them every 3 months minimum. Both the analog and digital are generally off a tick at that point. The Boveda "kit" works really well for calibration.
So your analog says 69 and your digital says 70. Is it rocket surgery? Does it matter? Long as they're in the same neighborhood, what's the big deal?
Had a beemer rider over here one time changing his oil. When he went to put his oil drain plug back in, he asked to borrow my torque wrench and wondered what the drain plug torque specs are. I refused. BMW means Be More Worried.
Are we likewise worrying for the sake of worry here? Even head bolts, a few inch pounds here or there is not the end of the world.
I trust that thing more than my digitals!
(yeah.......I just jinxed it.......it will be broken by the end of the weeknd)
I decided to calibrate my other 2 round digital and one analog. To my surprise the two digitals were off anywhere from 3-5% and the analog was spot on 75%.
Rectangle will always be off 5% but the other 2 being off????
I'm starting to think the analogs aren't given near enough credit.
And before anyone asks, YES I calibrated each of them for 36hrs with salt about 2mos ago.
