Precision Rated Optics Hand Held Power Meter (-20 To +26 DBm), With USB

The PM2 series of Power Meter are the advanced version of PM1 series. It is more functional and intelligent. Under the situation of laboratory, LANs, WANs and CATV as well as longdistance optical network, the Optical Power Meters, together with PRO’s Stabilized Laser Sources, can be used to identify optical fiber, measure optical attenuation, verify continuity and evaluate fiber link transmission quality.

Auto-Wavelength Recognition

The PM-202D unit can transmit with a wavelength-identification digital encrypted protocol, enabling the PM2 Power Meter to automatically use the proper calibration parameters. This feature reduces the need for communication between the two technicians and decreases the potential for error.

Referencing function

Signal encrypting can also give the receiving end information on the power to be used as reference, helping ensure efficient referencing, even when the two units are far apart.

Computer supported

Memory capacity of 999 data items; enables data transfer to a PC via USB connection. With the software, the date sheet can be saved as excle or txt, and print out directly.
