Workman Check-it Model Ultratec 870-330 Continuity tester ~Vintage~ This is used to check for electrical continuity in circuits or wires. "Check-it Model Ultratec was manufactured in Sarasota Florida suggest the manufacturing location or company base was in Sarasota, Flordia. Vintage testers typically use a light, such as a incandescent bulb or neon tube, to show voltage presence or a complete circuit. It measures 6.75" long. I do not know if it still lights up. This is a vintage item and condition is to be expected with age. This seems to be in really good condition
