Is Calibrating the AC Infinity probe needed?

You would need a properly calibrated hygrothermometer to compare. The probe is likely to be closer out of the box. You are right that averaged errors are still errors.

How should I proceed in this process? I feel as if I am about to make things worse if I just get an average of all the readings and offset the settings. Thank$!

If it’s new it should be close but you will definitely want to get an accurate hydrometer to calibrate. Those small ones are junk and go out of calibration in less than a year.

Those small ones in my experience are never even calibrated. Lol. Mine have all been off between 6 and 9% so like 3-5 rh% or so.

Never hurts to test em. I have found 24 hours or more to be ample time to really let them settle.

Calibrating and adjusting hygrometers - steps and questions

I am currently testing my hygrometers in a Tupperware bowl with the salt slurry. I understand how to calibrate my Bluetooth and wifi units, but my question is: Do the cheap ones that come in the 12 packs have any adjustment if you crack open the case? Or once they have settled out, can I just...

First off, the stated accuracy of most hydrometers is +/- 3%, or even 5%.

I use 62% Boveta packs to calibrate.

ACI probes are fast and the most accurate hydrometers I own. I tested two new ones recently and they were both about +1%, my 2 year old probe is -2%. In my tent, using ACI Cloudcoms with 0.1% resolution, the 2 new probes tracked within less than 1%!
The probes are great, but my damn Cloudcom won't graph or log data! They are too busy capturing the market to fix the bugs. :cuss:

My Inkbird probes are a few years old and still very fast responding, but not so accurate. Fortunately, they can be calibrated.
