Why no Farad or Henry meter?

[mawyatt]

We have Volt meters, Amp meters, Ohm meters, why no Farad nor Henry meters??

Best,

[tom66]

My multimeter has a capacitance meter... and I have an LCR meter in a storage box somewhere that can do henries, though it can't quite do farads (max 100mF).

So they do exist...

[mawyatt]

So why don't we call a meter that measures capacitance a Farad Meter (or uFarad meter), or a meter that measures inductance a Henry Meter (or uHenry meter)? We also call a meter that measures power a Watt meter???

Henry? - because there is the Henry Repeating Arms..

You don't actually measure units. You measure a physical quantity and the result is designated with a unit. It would be better if it was called a current meter, voltage meter, resistance meter, capacitance meter etc.

We know, however we have Amp, Volt, Ohm and Watt meters, but no Farad or Henry meters??

How about a "meter meter" to measure meters?

Perhaps the market is better for instruments with monosyllables in their name?

Gosh, amazing how many people miss completely the thrust of the first post, despite it being restated several times. But, sadly, that's what one expects nowadays - the viewer sees the words as they go past but doesn't really understand them

Nice (but shouldn't it be metre meter?).

Or a litre meter.

Thank goodness someone got the gist of this

In France, it is pronounced (roughly) "me tre", hence the spelling.
In America, it is pronounced "meet er", hence the spelling.

Depends on which side of the big pond, meter or metre and liter or litre!!

Here in GB it's hard to know which side of the pond one should stand on nowadays.

you obviously need a pond meter to give an indication of were you nee to be.

anyways back to the main event,could it be the size of the unit measured,very rarely do we measure 1 farad or 1 henry,its nearly always a fraction of the main unit.

We used to use VOM similar to RLC.  I think all of my meters are marked DCV/ACV for example rather than Volts.  Takes up too much room.

Amp, Volt, Ohm and Watt have the same implications irrespective of frequency.  To make a similar meter with Henrys and Farads, the error from parasitics and self-resonances must somehow be accounted for.  It is easier to pick a frequency and measure Ohms than it is to say with any certainty that this particular coil is 2.334uH at any frequency.

So, back to your OP. In German, volt-, am- and ohmmeter are respectively called tension, current and resistance meter (Spannungsmessgerät, Strommessgerät/Strommesser und Wiederstandsmessgerät), but I think those are the formal names. I'm not sure how German speakers refer to their meters colloquially.

In the beginning, the capacitance was measured in Jars, because the first capacitors were in fact pickle jars filled with water, from the times when electricity was thought to be some sort of fluid, thus the jars that were filled with electricity by electrostatic machines.

I still have some old spring type Pond meters in storage, which have been replaced by Newton meters. A real challenge for our American friends, since a single letter would change the unit - Pound force meters - while measuring the same physical phenomenon.

Make sure not to confuse with Newtonmeter meters (pound force feet meters?)...

We have LCR meters. The reason is that measuring pure capacitance (or inductance) is in practice of very little use, apart from quick checks, that many general-purpose DMMs embed. So that doesn't warrant a dedicated device.
Same for measuring "power". There's more to it than just a value in W, so there's no point in making a dedicated device just measuring that (what power are you talking about anyway?) But there are devices such as "power analyzers", that can measure relevant parameters around the concept of power. Just lie for LCR meters - because a single raw value has no real practical significance, unless again you just need "quick checks", that again many general-purpose devices will offer.

SiliconWizard;
Yours is the best answer, so far.

Real world inductors and capacitors have parasitic elements which should be accounted for if an accurate reading is to be expected.

horse meter vs horse power meter both useful
