But not voltage or current? Very odd common DVM, I'd say.

Can't say I've ever seen one with a scale marked "conductance" either.
Surely it's just resistance's other hat...

No conductance is differnt.

Someone from physics asked me if we had a resastivity meter.
We don't.

fx follows link

"Conductivity Resolution : 0.01, 0.1, or 1 μS; 0.01, or 0.1 mS"

It's measure in seconds?

Oh. Capital S not little s. I didn't know that. Nor do most of my
colleagues I think.

And given the hint from Mr Burns I go to Wonkypedia and find

"The siemens (symbol: S) is the derived unit of electric conductance,
electric susceptance and electric admittance in the International System
of Units (SI). Conductance, susceptance, and admittance are the
reciprocals of resistance, reactance, and impedance respectively; hence
one siemens is redundantly equal to the reciprocal of one ohm, and is
also referred to as the mho. The 14th General Conference on Weights and
Measures approved the addition of the siemens as a derived unit in 1971."

I stand by what I said. Conductance is resistance's other hat.

I may be ignorant, but I've never seen a multimeter with an inductance
scale. You can get little meters with inductance scales for component
measurement, but they're not usually multimeters as well.

I occasionally oggle these, difficult to justify for the rare uses the
extra features would get, in some reviews they compare well to Flukes

Hmmm ... twin thermocouples with delta display ... I suppose I could
balance my rads with one ...

It isn't uncommon for multimeters these days to have a capacitance scale
but I agree inductance is usually absent. They also often have a diode
and transistor testing option too. Most chipsets support it but it is up
to the maker to decide what functions they offer to the outside world.

Get yourself a £12 China special componen tester. Does most components, identifies pinout & gives secondary info too eg ESR.

Yes, I've got one of they.

Yup - very clever devices.

It often seems to be the case that the quality makes will concentrate on
meters that do the basics well, and eschew more exotic measurement
ranges, and then the others compete by throwing in everything but the
kitchen sink!

I'd like some with that option then I wouldn't have to visit the toilets to fill up the water bottles for the soldering iron sponges :-)

You could avoid even more visits to the toilets if you can argue
persuasively that urine is a "green" tip cleaner

It would have to be a *very* persuasive argument to explain why the
workshop smells like a pub gents' toilet. :-)

Also, not so much a 'green' as a 'yellow' 'solution'.

I just found out it recently is JEYES FLUID that makes gents toilets smell
like gents toilets ...
