Economical Handheld Laser Power Meter 843-R Newport

The 843-R is a low cost power meter yet capable of measuring power level from pJ and pW to thousands of Watts, in an ergonomically designed compact body.  843-R has two display modes: a large digital display with a bar graph or with a high resolution simulated analog needle.
A simple configuration of the measurement parameters and hot-swappable capability allow the user take measurements quickly even with multiple sensors. The case is made of molded high impact plastic with optimized angle kickstand. Rubberized sides provide an easy grip of the power meter and protection against damage.
