Calibrating my hydrometer

DukeHavana

I just got a new humidor for Christmas and it has a digital  hydrometer built in the front. I was wondering if there was any way to check the accuracy of it or should I trust it out of the box?

I would not ever trust it out of the box. Search the posts and I think you will find an in depth exlaination (too long to type with my thumbs right now). 

Just as an FYI I purchased the Boveda calibration kit which comes with excellent instructions and worked great.

You need to calibrate it.
It should just pop out.
I use a tupperware dish with sealing lid, and a 75% boveda, then leave it for 24 hrs.
Some use a ziplock bag

Thanks for the tips, I will see if it just pops out and go from there.

There's a thread on this forum about checking the calibration of Zikar hygrometers, that Zikar recommends checking them in Tupperware, not in a bag.  For some reason, maybe because of where the vents and the sensor is located the Zikar's don't read accurately in a Ziploc bag.  I checked the calibrations of my three hygrometers, stuck them in upside-down Tupperware with a Boveda calibration pack to check their accuracy, it worked well.

Just Calibrated my "Sensorpush" over 36 hours w/ Boveda's One Step Calibration kit. Worked well.
