hygrometers

need some info folks....do digital gauges need calibrated, or just the analog????



thanks

I'd imagine any digital gauge would need the occasional calibration. Are the old analog style a sealed unit ?? none needed there imo

Hygrometers are finicky and difficult to calibrate, thats why most dont use them...RH is close enough.

Don't buy anything marketed for "hydroponics", its cheap Chinese shit. I should know I deal with shitty products every day since all wholesalers will only carry cheap shit. http://bamboozoo.weebly.com/your-humidity-may-be-way-off.html

Why not buy a bunch of cheap hygrometers and calibrate them to each other?

They are available on Amazon/eBay regularly.

Beats the $45 I saw for a caliber at my local smoke shop.

I bought 3 or 4 digitals last year...the 2 I have found agree...I'm runnin' em!!!!
