Economical Handheld Laser Power Meter, 843-R

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.
843-R can be operated either by battery or from an AC source with the charger plugged in at all times. Its backlight allows illumination of the power meter in low light conditions. Recalibration in every 12 months is recommended.

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.
