The 842-E-USB is a powerful dual channel virtual optical power and energy meter, compatible with the Pyroelectric Laser Energy Sensors (and the legacy 818P Series Thermopile Detectors). After installing the software, your computer turns into a power meter.



Features

Utilize the Full Computing Power

By installing the software (compatible with Windows7 32 bit and 64 bit), turn your computer into a power meter and utilize additional computing power for data storage and analysis.

10 kHz/Channel Measurement Rate with a Trigger Input

The high data transfer rate allows downloading data at 10 kHz/channel allows taking data for an energy measurement for every pulse with the Pyroelectric Laser Energy Sensors. An external trigger is available for 3 V to 24 V trigger input with an adjustable trigger level to synchronize the data acquisition with the laser source.

Intuitive Software Package

The software features include a complete statistics package including Min, Max, average, standard deviation, root mean square, point-to-point stability, pulse count, and repetition rate, a line plot and a histogram, and options for saving data, saving statistics, or both. The screen can easily split into multiple windows with various displays.
