[Shop-talk] Measuring ozone

[lee at automate-it.com]

Pat,

It's a tough question - if you've got $XX,XXX then you can get a great 
environmental-lab quality monitor, and it will work well, accurately, 
for a long time. Like this one from Thermo-Fisher 
https://www.thermofisher.com/order/catalog/product/49IQ. But I know 
that's not in the plan.

For $100+ it looks like you can get this Chinese option - reviews are 
not too bad, but who knows?

But since I'm a chemist with access to ACS publications, I've attached a 
paper from Journal of Chemical Education (2005), describing how to set 
up a lab experiment for undergrad students to make this measurement. Not 
expensive if you already have a lab set up - but will likely cost you a 
lot more than the Chinese monitor just to put together all the reagents 
and equipment. Still, it may provide enough info to give you some ideas 
about how to go about doing this. So, enjoy!

There's a relatively inexpensive
