Neat stuff you are doing there. The problem with those analogs from the pet store is not that they are never accurate. I am sure there are a couple in a batch that are. The problem is that the build quality sucks and I have zero confidence that even two would give you the exact same reading. Analog is still great in my book, but a good analog anything requires at least periodic calibration. I have serious doubts that for the price of those gauges that they are or even can be calibrated. That said, I personally take humidity readings with my finger and it works for me. Don't ask. It's voodoo. lolOriginally Posted by Mike17
I used to have a round clock type from petco therm and humidity... I got freaked out by everyones' comments so I made myself a PID thermostat, 0.01 degrees error and 0.03% error deviation on power output. Meaning: industrial grade, extremely precise.
I'm waiting for the hygrostat I ordered directly from honeywell to install it on the other side of the HMI.
Just to find that my $1 petco clock type therm is spot on every time I check on it.
So yes digital is more accurate and reliable but in my experience analog did just fine. and we're talking of a bill difference of $1.75 analog vs. $214 digital.
just saying.
