Trolmaster help with humidity control

[Mayz92]

I’ve noticed there is a 5-6% difference in my trolmaster humidity reading vs the two hygrometers in my room. Is this because the trolmaster is more accurate? Or do I need to calibrate my trolmaster? The devices are brand new

I’d probably rely more on the trolmaster. What unit is it?

I had to laugh reading this. I had similar discrepancies on different units. The quest der units always read way lower than the trol masters and cheaper units. I had 3 infrared thermometers; they always were about a degree off from one another. I misplaced one for a flower room and picked up a newer more expensive option, it is always 6 degrees higher than the other 3.lol. You dont even want to buy air pressure gauges for aircraft, they all read different. Quite frustrating at times when trying to figure vpd and your leaf temp may or may not be accurate. Their is someone out there that could figure this all out, i go home and watch hee haw and it all goes away for awhile.
