Economical Handheld Laser Power Meter • Compact handheld design with rubber bumpers and a • Digital value display with either bar graph or a simulated analog needle •Analog output •Single shot energy measurement with a thermopile sensor • Compatible with Newport photodiode detectors and new 919P series thermopile sensors •Backlighting and rechargeable battery 843-R is a low cost Laser Power Meter yet capable of measuring from pJ and pW to thousands of Watts, in an economically designed compact body. It is compatible Newport's 818, 918D, 819C/D series photodiode sensors or the new 919P series thermopile sensors. A single shot energy pulse measurement can be done. 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. Th 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. 843-R can be operated either by battery or from an AC power supply (included) with the charger plugged in at all times. Its backlight allows illumination of the power meter in low light conditions. Note that the 843-R Optical Power Meter is not compatible with the 818P series Thermopile Sensors and the 818E series Pyroelectric Sensors.
