The Model 842-PE Handheld Optical Power/Energy Meter is a powerful tool that is also easy to use and intuitive enough to master in minutes. While the handheld style makes it great for field service, this meter can also be networked via USB or RS-232. A special USB cable is included, while a special RS-232 cable may be purchased separately.
The 842-PE laser power/energy meter has a DB15 input connector for direct compatibility with Newport's 818P thermopiles, 818E pyroelectrics or 918D and 818-xx/DB Series Low power semiconductor photodiode detectors.
Note: The 842-PE ships with a power supply.
