Extech EX350 11 Function True RMS Digital Multimeter - In Use

This professional digital multimeter measures a total of 11 different parameters, making it ideal for any basic electrical measurement application.

The EX350 tests AC and DC voltage, AC and DC current, resistance, capacitance, frequency, duty cycle, diode and continuity. It also comes as standard with a built-in non-contact voltage detector, allowing it to be used to verify the presence of voltage on a live circuit before testing.

Equipped with a true RMS mode to ensure accuracy when testing on irregular AC waveforms, the EX350 also includes low impedance to filter out ghost voltage false readings and a low pass filter (LPF) for performing accurate measurements on variable frequency drive signals.

This multimeter comes with a range of additional features including a relative mode for capacitance zero and offset adjustment, data hold function which will freeze the current value displayed on the screen and a MAX/MIN mode for calculating the highest and lowest values taken over a time period.

Extech's EX350 is CAT III 600V safety rated and is supplied as standard with a 3 year warranty from Extech.
