KEYSIGHT TECHNOLOGIES' U1233A true RMS 6000 count handheld digital multimeter with non-contact voltage detector is the best HH-DMM for the conditions you work in. Whether it's dark, noisy, or even dangerous, the multimeters help you prepare for these conditions with features that anticipate worse-case scenarios, but make everyday tasks easier. Using just one hand, you can illuminate the test area with its built-in flashlight while you measure and change or choose measuring functions. You could safely detect hot wires and easily make continuity measurements in noisy environments using the unique combination of beeping alert and blinking display/LED. Whatever the working conditions, we have it covered.
