I’m uncertain about those cheap meters - someone needs to buy one and have it delivered to me and I’ll run it against my pAwkit and see how it compares - send back if crap - forward on if not.
Sounds like an interesting experiment. I know that if the pH is low then you can have a higher AW without it affecting the shelf life as much but i'm not exactly sure what the ranges for these things are.
I came across a paper that estimates the AW by using a formula using brix and pH measurements. I imagine pro-choc probably uses something like that.
I'm going to buy one of those cheapo water activity meters so it would be great to see how they compare to the pAwkit ones. They still work out cheaper than a pro-choc subscription, so worth a try i guess.
I live in the UK though, so not sure if there would be some weird Tax rules/rates if I send it Canada and then you send it to me?
