Avo light meter

[ipf]

Came across this tiny old light meter tucked away in stores. There's a side button to change readings to X5.

Shame the input glass is broken...but it still gives reading.



It's getting on a bit......gives a light source factor for 'gas light'.

They must have had some designer AVO, they're classics in the looks department

What's the light source factor

I presume it's where you derate the reading depending on source

Zoom in on the last photo...... rating factor applied for different types of lighting.

Ya I saw it took a few minutes to realize what it was

Im googling luxmeters but I'm not seeing any analogue ones in the results

Presumably they'd have the advantage in some situations that you get with analogue clamps and Meggers that you can see fluctuations quicker

I dunno does that apply with luxmeters,.never used one

Nice Light Meter ?
Their first multimeter was produced in 1923. All dc ranges! Wish I could find one!
They made many different meters and items of test equipment (signal generators, valve testers, even geiger counters for civil defence). Interesting article on Wikipedia if you like that sort of thing.
sold on fleabay recently:

I wonder what the accuracy is like on the old stuff

Did they have calibration back in those days ?

The vintage avo stuff is cheap, investment opportunity I reckon, helps if you know how to repair them
