Here is what is says at the BH site about the Ilford enlarging meter.
It sounds very complicated! I trust it's not as hard to use as it
sounds?
Like anything, it can be simple to use or complicated to use.
It depends on what you want to use it for.
If you want to use it for anything other than seeing if two
spots are the same brightness then things get complicated
fast.
It isn't calibrated. It isn't linear. No two agree with
each other. There is no published data relating EM-10 readings
to anything.
With a lot of hum and haw it is possible to use it as a light
meter/densitometer by comparing the light a negative
lets through to the light a step tablet lets through.
- Or -
You can buy meter designed for measuring light in
a darkroom environment: calibrated, linear, published
curves, determines paper grade, reads exposure time,
tells you how much to dodge, tells you how much to
burn, and reads negative density to 0.01 stop.
It even works dandy emulating an EM-10 at comparing two
spots to see if they are the same brightness.
And, it is a _lot_ easier to use than an EM-10.
