UNITY DT-830D Digital Multimeter

The UNITY DT-830D Digital Multimeter is a widely used and affordable tool for measuring various electrical parameters. It’s a great choice for mobile technicians, electronics repair, students, and DIY enthusiasts.

Digital Multimeter?

A multimeter is an electronic measuring instrument that combines multiple measurement functions into one unit. It can measure voltage (voltmeter), current (ammeter), and resistance (ohmmeter). Advanced models may also test additional properties like capacitance, frequency, temperature, and continuity, making them essential tools for diagnosing electrical circuits and components.

Features:

The Unity DT830D multimeter is used to derive the measurements of DC voltage, AC voltage, DC, resistance, continuity, and diode with a high degree of accuracy. This is the manual ranging multimeter so the user is required to select the correct measurement range. It is a very user-friendly device just turn the rotary dial to the test you need and place the test leads accordingly and you will get the reading.
