The DR-7 direct-reading ferrograph from Trico Corporation measures the concentration of wear particles in lubricants while providing basic wear-trend data to help determine equipment condition within minutes. It uses magnetic gradient to trap and optically measure ferrous wear particles on a scheduled basis. It establishes the baseline wear level; any sudden increase alerts the user to potential problems. It runs on PC-controlled hardware and can incorporate external devices via a four-port USB hub. It has an internal microprocesser that serves as a diagnostic system and has a 7-inch LCD display and an Ethernet port. 800/558-7008; www.tricocorp.com.
