The 843-R low cost power meter is capable of measuring power level from pJ and pW to thousands of Watts, in a 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 to take measurements quickly, even with multiple sensors.
The 843-R includes a calibration certificate, a plastic case, 843-PS-UN, a convenient quick start guide and a 2.5 mm analog output connector.
Note that the 843-R Optical Power Meter is not compatible with the legacy 818P series Thermopile Sensors and the 818E series Pyroelectric Sensors. Consider purchasing the 843-R-USB for a USB interface with a PC.
