Sorry for the multiple post but....
Alibaba's description .vs. when you go to the actual companies website which is in Finland, is a bit different on the model number.
On the companies website, it lists specific meters for specific things, and coffee is a separate category.
On AliBaba, they are notorious for generalizing, ie they love to use a ton of 'keywords' to get you to their page, then its up to you to try to figure out if that product is what you wanted or not.
Manufacturer -
We have a meter, it has 7 different 'setups' or models, and can measure moisture in 65 different mediums. Choose what you want to measure moisture in and then get the correct model for your specific product.
Alibaba - We have a meter that measures moisture in 65 different mediums, only 140 dollars! You go now!!
Be careful when dealing with them, KNOW the exact specs of what you want and the exact model number. Don't trust their write up that it's what you really want.
