I am not sure if such a device exists, but I would recommend contacting a company that specializes in measuring arsenic levels.

I didn't read the references provided by bored chemist but i'm familiar with the marsh test and it's quite easy to do with a small quantity of acid and some simple glassware and it's quite sensitive. As far as I remember it will also give a positive with antimony. When it was invented it put a stop to the use of arsenic trioxide as "inheritance powder". I don't think arsenic is used or has been used in consumer products for a long time. It's only use today is in metallurgy, semiconductors and believe it or not, as an anti-cancer drug.
