Digital Multimeter Model MTX 3291

The Model MTX 3291 is a portable multimeter that measures voltage (AC and DC), resistance, capacitance, temperature, duty cycle, and frequency. The meter performs continuity checks and diode testing (including forward bias voltage), and includes an AC voltmeter function with low input impedance for finding ghost voltages. Other features include monitoring Min, Max, Avg, and Peak measurement; Auto Range mode, and Data HOLD.

The meter is compact, rugged, comfortable to grip, and waterproof to the IP67 standard; and is rated for safety (EN 61010-1, NF EN 61010-2-30 1000V CAT III, 600V CAT IV).
