Anyway, don't hope for a miracle with the new hygrometer as they come from the same manufacturer.

digicabi uses salt tests on the hygrometers they sent me
I use western caliber digital hygrometer which they claim is as accurate as it is that needs no calibration.
Both my hygrometers are within +/-1rh during the salt test and inside my dry cabinet.
I have used western caliber for years to gauge rh even after the hygrometer broke down in one of my older dry cabinet and I never had any issues with fungus.
It may not measure up to your industrial probe but I am comfortable based on the above and the consistencies.
When put in dry cabinet and the humidity probe shows 48%RH, the WCs show 40%RH.
I have 4 Hygroset hygrometers too, the difference between Hygroset and WC is +8% RH (for Hygroset).
Hygroset can be calibrated, which is good. For cameras and electronics, 35% to 55%RH is unlikely to cause any issue.
I'm more critical with the RH inside my dry cab as I place wood instrument inside. Long term storage below 40%RH will cause the wood to crack. High humidity will cause the wood to 'bloat'. So I invested in an industrial humidity probe to be safe.
Faint, my view is that there is no need to be too concerned about it being off.
What is the purpose of buying dry cabinet? To see a number appear as you want it, or to keep your camera gear safe? I think most people here are commenting on other things because they don't priotize the appearing number, merely whether the dry cabinet absorbs humidity properly. One has to keep in mind that you aren't buying a precision tool here, merely something rough enough. I think it's your choice to take it up with the company, but at the same time, I would comment that there are probably more constructive things to do with your time, since the dry cabinet at 42% will indeed meet the basic goal of ensuring that your camera equipment won't grow fungus, and isn't too dry either.
