Njty 1999 maximum display digital multimeter manual gage with flashlight lighting backlight
Fear of burning errors when you first use a multimeter want a more accurate range display (2000 counts), ahead of current technology? You can choose our njty multimeter.This new multi-function multimeter has a high precision and high performance mcu processor, which can measure dc/ac voltage, dc current and resistance.It can also test ncv (non-contact voltage), transistor hfe, diode and conductivity.The back is supported with a bracket that can be easily placed on the table and read.
Characteristics:
199 counting and multi-function: 2000 counting can be displayed and ac/dc voltage, dc current, ncv, resistance, conductivity, diode and hfe tests can be tested by magnetic adsorption.
Precision circuit boards and overload protection: resistance measurements using glass tube fuse, shielding interference and continuous testing can reach 30.
Multi-purpose options: ncv tests with visual and sound alerts can ensure your life safety, data maintenance, and auto-power shutdown.
Easy to use and read: large lcd display with back light, easy to use, is an ideal home-based tool for laboratories, factories, radio enthusiasts, etc.
Portable design: there is a back-up bracket to support the multimeter and test probes can be collected for your convenience.Bright flashlights can be easily measured in the dark.
