Feature

●*Precise testing, fine workmanship, easy to carry, completely replace the optical power meter
●* In the era of high bandwidth, reliable fiber optic power equipment is especially important. This handheld photometer can check the performance of the cable to help calculate relative power loss, search failures and troubleshooting
●* Measure the length of network cable, coaxial cable and phone cable. Can test open, short, and cross connects
