Low Cost
Small Form Factor
USB interface with Intuitive Application Software
Compatible with all Photodiode Detectors and 818P Thermal Detectors
The Model 841-P-USB is a Power Meter with a USB connection to use a computer as the monitor, allowing the user to access the full computing power of the computer.
841-P-USB is the most economical choice for an optical power meter even though it offers extensive features with great connectivity. Its low cost and small 86 x 58 x 27 mm form factor make it an ideal tool in a manufacturing setting, busy labs with small workspaces, or in a suitcase of a field service engineer.
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. The device is powered via the USB cable, which is provided with each unit. With an intuitive software application similar to that of the 842-E-USB , the user can take full control of the meter within minutes.
The Model 841-P-USB Virtual Power Meter is easy to use and intuitive enough to master in minutes. A USB cable is included with the meter to connect to your PC or laptop computer, though which the device is powered up. Using the same screen, the user can set the data sampling parameters. It is easy to recover from measurement interferences. For example, the last value or the last period in the statistics buffer can be canceled, enabling you to continue without stopping your work. There are also many options for saving data, saving statistics, or both.
