Extech EX411A 8 Function True RMS Professional Multimeter
The upgraded version of Extech's EX410A digital multimeter, the EX411A includes all of the functionality of the 410A, but is also true RMS and will maintain its accuracy when testing AC.
A manual ranging digital multimeter, the EX411A can measure AC voltage from 1mV to 600V, DC voltage from 0.1mV to 600V, AC current from 0.1mA to 10A, DC current from 0.1μA to 10A, resistance from 0.1Ω to 20MΩ and also performs diode and continuity tests. This multimeter is also supplied as standard with a type K bead wire temperature probe, allowing the meter to be used to measure temperature from -20 to 750°C (-4 to 1382°F).
A large size, backlit LCD screen with 1 inch high digits makes it as simple as possible to view all measurements on the EX411A. It also includes a rotary dial for selecting measurement modes and a data hold function which will temporarily store the current values shown on the screen.
This digital multimeter is CAT III 600V rated.
