Hi,
Looked at this route lots, and the types of companies offering great software as well (like Safefood 360).
For our company though, the problem was that the products we were producing were cooked brined meats so there was a lot of salt/nitrates in the air - which corrodes iPads for fun.
We looked at housing them in waterproof rubber units so at least if they dropped they had a better chance of survival, unfortunately we just couldn't get them to work effectively. The nail in the coffin for us was that one was placed on a table in production for a couple of hours whilst we were doing some investigatory work and when we returned it had vanished. We had interviewed staff, threatened them a little with the police, and blocked the iPad through the Apple website however these are very expensive and highly sought after units so there is always that risk (which we found out). Unfortunately, the unit that disappeared had a lot of QA data on which we lost.
If you do go down that route, just remember to put them on the glass and hard plastic register.
Thanks
Simon
