With 11 different functions available, the Extech EX430 is an essential tool for testing practically any electrical parameter.
A true RMS digital multimeter, the EX430 is extremely accurate even when testing on irregular waveforms. It's also auto-ranging, and will automatically select an appropriate range for the test that's currently in progress.
This DMM can test AC voltage to 600V, DC voltage to 600V, AC/DC current to 10A, resistance to 40MΩm, capacitance to 100μF, frequency to 10MHz, temperature (using a type K probe) to 1382°F (750°C) and can also perform duty cycle, continuity and diode tests.
Extech's EX400 series consists of several different multimeters, each made to fit the needs of professional users. The follows options are available:
