Would I get good accuracy mixing epoxy and catalyst by weight?
Rather than volume?
I want to mix the epoxy in small quantity which makes it require accuracy, so I thought I could use the digital scale. The proportions must be exactly equal.
Thanks for all answers. This is bar top epoxy which seems to be very intolerant of imbalance. The only downside I know of is stickiness, but a sticky underside to your finder is not on my list of defects. It should be volume, correct. But I would have much trouble to measure by volume while I can do a good job by weight.. I am going to assume it will be close enough even though one's densitiies are less.

I though the epoxy & catalyst were formulated to match by volume. If the manufacturer wanted you to match by weight, they would say on on the label. If all else fails, read the directions!

As long as both components weigh the same, this would work, but if the epoxy weighs more or less than the catalyst, you'd just end up with a sticky glob.

you can visually inspect for viscosity/density and get an approximate answer.
you will never find an "exact" proportion. the epoxies are probably even formulated for a specific margin of error. The plunger and mixing mechanisms are fairly crass when it comes to exacting measurements.
