Inquiry (采购产品): Looking for a sensor I am looking for a sensor that can detect black or dark particles in a clear container of salt crystals. We have a clear ABS plastic container that houses salt crystals. We sometimes see impurities in the salt that end up inside the container. Do you have a sensor you can recommend I take a look at? The container is capped with a black non-removable cap so it would have to sense from the side of the container and be able to see through the crystals in the container and detect dark small pieces of impurities. **** Hidden Message ***** Steven Pellnitz 93030 Company: Olde Thompson E-mail: steve@oldethompson.com **** Hidden Message ***** steve@oldethompson.com
