The T+PRO is a handheld electrical tester and voltage detector designed to provide rapid indication of voltage levels, faster and safer than traditional solenoid testers. It features a maximum working voltage of 1000 V AC/DC with a maximum measurable voltage of 600 V AC/DC, an LCD display with accuracy of ±(3% rdg + 2 digits) for AC voltage and ±(2% rdg + 2 digits) for DC voltage, and multiple LED indicators that illuminate at nine preset voltage levels (12 V, 24 V, 48 V, 120 V, 208 V, 240 V, 277 V, 480 V, 600 V). The device operates over a temperature range of -10°C to 55°C, is powered by two AAA batteries with a 40-hour life, and complies with safety standards including IEC 61010-1 CAT III/600 V CAT IV and NFPA 70E. The T+PRO is ideal for electricians and maintenance technicians who need a reliable, portable tool for voltage detection and measurement in residential, commercial, and industrial electrical systems.
