Inquiry (采购产品): odometer/counter I am looking for a device that can be used to count revolutions on a "hamster wheel". We need to measure the activity level of hamsters in differnt circumstances. Do you have a device that can be attached and will count the revolutions? Thanks, Dug Jones **** Hidden Message ***** Dug Jones 32607 USA Company: Santa Fe Community College Title: Asst.
