Optical Power Meter, Economical Handheld, Laser Power & Energy
The 843-R-USB has the same performance as the 843-R, with the addition of USB communication to a PC. Install PMManager to use with the 843-R-USB, and your PC becomes a full optical power meter workstation. A COM object for system integrators, as well as a LabVIEW library are provided. The 843-R-USB low cost power meter is capable of measuring power level from pJ and pW to thousands of Watts, in an ergonomically designed compact body. All compatible detectors are hot swappable. 843-R-USB 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 843-R-USB includes a calibration certificate, a plastic case, 843-PS-UN, a convenient quick start guide, a USB cable, a 2.5 mm analog output connector and a PMManager quick installation guide.
