The UT139 series are CAT III 600V digital multimeters designed for electricians. The NCV feature checks for live voltage by sensing electromagnetic field intensity. The new UT139E/S models add special features such as LoZ (ACV) for measuring "ghost" voltage. The built-in 31-segment analog bar gives a better visual representation of results. The UT139S has a black EBTN display and is ideal for working in dark environments.
