Thread: It always amazes me when...

  1. #1

    Default It always amazes me when...

    ...photographers somehow think that digital technology is superior. For example, people think a dry cabinet with a digital hygrometer is somehow more accurate and better than one with a non-digital hygrometer. And they'll pay more for the fomer!

    The truth? The measuring instrument (ie the part that senses the air humidity) is a mechanical, analog device! There's some kind of circuit to convert the reading to digital, but the digital reading is only as accurate as the analog sensor to start with.

    So why pay more for a digital dry cabinet when it costs more to purchase and operate (battery cost)? Your analog meter needs no power, and if calibrated, is just as accurate!

    Beats me.

    Same applies for many other things-- bathroom scales, thermometers, light meters, etc.

    Digital costs more, eats batteries, and has no advantage-- yet people somehow think digital is superior.

    So I presumed you used an analog computer to start this thread?

    I'm tempted to quote a certain hokkien phrase but alas, what you had said hold no weight at all. Electronic hygrometer and thermometer does actually utilise a capacitive or resistive sensor and silicon bandgap temperature sensor respectively which can be fabricated into an integrated circuit.

    Are you flagging the dead-horse-film is superior than digital anal debate?

    The purpose of your lecture?

    give up

    Dunno. I don't own a dehumidifier and I know (or I think I know) that my digital cameras are a LOT better than my film cameras

    If it's measuring a change in resistance or conductivity, it's an analog device. So what if you convert the analog measurement to a digital reading?

    Maybe you need to read again. This is highlighting some people's misconception that eg a digital thermometer is more accurate than a non-digital thermometer.

    For certain devices (eg quartz watches vs mechanical watches) yes. But certainly not for everything. Yet people are so easily misled....

    I think that's quite a far stretch. Analog scales uses mechanical moving parts.

    In engineering, we always try to reduce the number of moving parts because that's usually the part that fail 1st.

    How many moving parts does a mercury thermometer have? What about battery dependency of a digital thermometer, possibility of battery leak, etc.?

    and the whole purpose/objective of this thread? IIRC, Digicab (digital hygrometer) is cheaper than Akarui (analog Hygrometer)?

    I really feel that a digital thermometer is better as I can get the result faster. In fact, I also do not know how long I need to keep the mercury/alcohol thermometer in my mouth before I take it out to show my actual temperature. 5 mins?

    i m more amazed when i saw them descending from the trees

    OT liao.

    well, anal versus dig,
    preference is up to individual.
    as long as mission accomplished,
    i for one don't care how.

    today's superstitions is tomorrow's science,
    someday, something will replace the digital god.
