BK391B

BK391B is a true RMS handheld digital multimeter. It offers a comprehensive solution for general purpose measurement applications. Bundled with a complete set of accessories, this multimeter provides technicians and engineers with accurate results, data logging capabilities, and measurement features for evaluating a variety of electronics or electrical systems. The easy to read display features an analogue style bar graph to help identify measurement trends or fluctuating signals. Dual line display capabilities enable two measurements or one measurement and a math function to appear on screen simultaneously. The advanced features like data logging records measurements to the meter’s internal memory at a user-specified sampling interval. Additionally, measurements stored in the meter's internal memory can be exported using the provided PC application software.
