| The FeverTags Beef Cattle Ear Tag is a light weight (1 oz), easy to use, cattle temperature detecting device. Installed like most visual ID tags the FeverTag is made from durable weather resistant poly-carb plastic. The heart of the device is a computer microprocessor that monitors core body temperature. Once a fever is detected an ultra-bright light will turn on signaling you that the animal has breached normal temperature and warrants further attention. |
