Has anyone used one of these before?

https://www.atlas-scientific.com/produc ... h-kit.html

I emailed them and they do have a lot of customers using it for dry curing meat. Curious if any of them are here. If so how has it worked out?

I'm considering adding it to my raspberryPi project. I'd then have temp, humidity and PH available.

thanks,
dave

I like the idea of using a raspberry pi, I was looking at Arduino for a control unit myself. My personal thoughts from a quick look at the site is that it doesn't seem worthwhile. Typically you'd check pH a certain points in the fermentation to start of drying part of the salami making but having a dedicated meter and incorporating it into a larger system just seems unnecessary. I just went with the pH strips and am thinking about an electronic unit but until production goes up the strips are inexpensive and meet my needs.

I just bought the PH-12 from Germany, after doing some research, & I think its the best one out there for the money.

dpeart, if you can successfully integrate it into your other gauges, then I think it's worth the try. Looks way too complicated for an old techno peasant like me. At the same time, if you are getting into salumi, the ability to monitor the PH is indispensable. PH strips are not precise and most of us have a degree of colour blindness. It is often impossible to tell the difference between a 5.5 and a 4.8 reading, and yet the difference can mean success or failure. And I have always been wary of the method of mixing one part meat with two parts water and then sticking a strip into the mess.

Go for it, and keep us informed.

I also got one recently. Used it on one batch and it seems to work well. But the marketers should also disclose that the meter is actually designed for soil testing and made in Taiwan and not in Germany. When I open up a tin labelled "tomato soup" that is what I expect and not something that is only related to tomatoes.

But the jury is out and I will pass judgment in a couple of years.

Well I just sent my PH meter back last month because I couln't get it to calibrate. I'll have to use those dreaded PH strips in the meanwhile!!

Now you know why I went back to Ph papers.

The bulb on/in the probe does not last very long (in almost any Ph meter)

It is also the most expensive part of the unit to replace.

Hmm, mine is still working, I recalibrated it a few days ago and it was off by only .04. Hope it lasts because I hate using strips.

Yeah but still Bob it shouldn't have gone that fast! :sad: I have only used it like 3 times since I bought it last April.

I agree but even on the more expensive units like the Hanna HI 99163 the probe/electrode is warrantied for only six months.
