Gardner Bender GMT-319 Multimeter Tester - Analog 7-Function Tool

In this review the Gardner Bender GMT-319 Multimeter Tester is evaluated for homeowners, hobbyists and field technicians who want a straightforward analog meter with manual range control and a large, easy-to-read face. The biggest reason to consider this unit is its clear color-coded analog display and simple 20 position rotary dial that make quick voltage, resistance and continuity checks fast and intuitive without navigating digital menus. It is a practical choice when you prefer an analog readout and fuse-protected current jack for routine electrical troubleshooting.

Key Features

• Manual range selection: The 20 position rotary dial gives direct access to 19 ranges so users can set the meter to the exact scale needed for more controlled readings.
• Easy to read display: The large, color-coded analog face reduces eye strain and makes it simple to interpret readings at a glance, especially for older eyes.
• Multi-function testing: The GMT-319 measures DC voltage, AC voltage, DC current (fused jack), resistance, megohms, continuity with buzzer and household battery tests for versatile troubleshooting.
• Safety protection: Agency approved design includes fuse overload protection circuitry to help protect the meter and the user during current measurements.
• Accessories included: The kit arrives with replaceable test leads and operating instructions so it is ready for use out of the box.

Who It's For

The GMT-319 is aimed at homeowners, hobbyists and service techs who prefer an analog instrument for simple diagnostics rather than a digital display. Its large face and color coding make it especially helpful for users who prioritize readability and want to perform quick voltage or continuity checks without learning complex menus.

Those who need highly precise laboratory-grade resistance or modern data logging features should look elsewhere; this is a straightforward analog meter and some users report mixed accuracy in ohms mode, so it is best used for general troubleshooting and not precision calibration work.

Pros & Cons

Pros

• Well-made analog design with a large, readable face that many users find easy to use.
• Wide functionality in one tool: AC/DC voltage, DC current (fused), resistance, megohm and continuity with audible buzzer.
• Safety-minded construction with fuse overload protection circuitry for current measurements.
• Compact size and included replaceable test leads make it convenient to carry and service.

Cons

• Some customers report mixed accuracy in ohms mode, so it may not be ideal for precision resistance measurement.
• Analog meters have lower resolution than modern digital meters for detailed numeric readouts.
