accessory instruments

Just a quick query on opinions. I am looking for a replacement voltmeter of
quality. I appreciate that such accessory instruments are only 'indicators'
and not supposed to be as accurate as say a multi-meter. A couple of years
ago I replaced a dodgy 'Durite' voltmeter (a make which is usually regarded
as good industrial quality) with a 'TIM', a make which now appears to
dominate the accessory scene. But that too is now over a volt and
half too slow.
So is there a good quality range of 50mm instruments out there or do I go
digital? In the past I have used the alleged high quality 'VDO'
instruments but despite their 200-300% price premium, they appear to be no
better than Durite in performance/longevity. Help appreciated thanks.
Cheers

Yesterday I was cruising the web looking for ammeters and I came
across the manufacturer of meters that are calibratable, forgotten the
site but I'll look again today.
Regards, Clive.

Why not giving the RS site a try for industrial grade digital
voltometers? I have an LCD meter that uses only two terminals (12V and
GND) and is the simplest ever to fit. It's the right range for the
on-board installation and is accurate enough (four digits).
As for the ammeter, you can use the same unit with a calibrated shunt
load and measure voltage drop across the shunt resistance. One or more
switches cxan be used to commute between two batteries and fuctions
(volts/amps).

Thanks Clive and Roman,
Look forward to your suggestion Clive when you get the info thanks.
Roman, thanks for reminding me that I have an RS account number !! I will
have a look at them when I am next near a landline and can browse their
sometimes infuriating website. I have gone through my Maplin catalogue
which I always keep at hand on the boat, but with little success. Pity
Ilkeston don't have more instruments to chose from other than Durite. (Oh
for the return of Smiths instruments).
Look forward to more suggestions from others, thanks.
