Features: 3-in-1 Electrician's Tool: a mini pen type tool is a multimeter & IR thermometer & test pen, which integrating three functions into one, thus it is very perfect for home, office, laboratory, factory, and other application. Multimeter Function: including 60V DC/AC voltage measuring, NCV voltage detection, resistance, frequency, continuity, live wire detection, etc. The upgraded voltage sensing probe provide ultra-high sensitivity detection. Infrared Thermometer Function: -20~380C / -4~716 infrared temperature testing range, very simple and safe to take the temperature with this digital pen-type thermometer. Live/Neutral Wire Check: safe and easy to distinguish the live / neutral wire by comparing the strength of the detected voltage, the wire that detect the stronger voltage signal is live wire. VFC Test: VFC function can measure the output voltage of inverters. Compact & Reliable Design: sturdy and durable ABS material with 2m drop resistance, upgraded chips to guarantee the high accuracy test result and with full measuring range overload protection to ensure safe testing process. Low Power Consumption: the multifunctional meter just powered by 2pcs AAA batteries(NOT included), with low battery indicator to remind you once the battery need to be replaced, it can automatic shut off to save power if no signal input for about 15 minutes. Package Include: a pair of test lead, a mini cross head screwdriver, and a high-quality zipper EVA carrying case, easy to operate, carry and store.
