btw nothing wrong with analog hygrometer they are easy to test and calibrate .that's like saying my analog volt meter is **** when it can actually be more accurate than a digital one because of emf effecting the digital can cause slight spikes and variances as can a low battery etc... proximity to other power sources(aka lighting , heat lamps, and under tank heaters ).the variance between the 2 can be so small it is negligible.
Did i mention i am also a licensed electrician as well as mechanical engineer lol. My wife has a degree in electrical engineering .the thing is everyone is going to digital nowadays , nothing wrong with that but the reasons are simple digital things wear out faster than analogs thus marketing has gone to them .Its profitable.Sincerely RSKING CEO RSKING MECHANICAL & ELECTRICAL AKA ZIGGY STARDUST.
