The nVent GARDNER BENDER GMT-319 is a professional-grade, multifunctional analog multimeter designed to handle a wide array of electrical tests for homeowners, hobbyists, and professionals alike. Capable of measuring 7 essential functions across 19 different ranges, this unit is the ideal tool for troubleshooting household batteries (1.5V and 9V), testing wall receptacles for proper grounding, and identifying breaks in light strings or electrical cords. The GMT-319 features a high-visibility, color-coded analog display with a mirror scale to significantly reduce parallax errors. For added convenience during circuit testing, the unit includes an audible continuity buzzer that sounds at less than 100 Ohms. Precision is further enhanced by the integrated Zero Ohms adjustment dial, which allows users to calibrate the needle prior to resistance testing or when performing internal battery checks. Safety is paramount; the GMT-319 is agency approved and incorporates fuse overload protection circuitry to protect the user. It is capable of measuring AC/DC voltage up to 1000V and includes a separate fused jack for measuring DC current up to 10A. Whether you are performing bench work on electronic circuits or checking the charge level of common batteries, this tester delivers reliable results. Each unit includes replaceable test leads to get you started immediately. (Please note: The decibel feature is intended for transistor gain measurement in electronic circuits and should not be confused with audio decibels.)
