Today I am reviewing the Triplett LVPRO30 and LVPRO30SR Low Voltage Pro Cable Testers. The Triplett LVPRO30 Low Voltage Cable Testers are great for installation and maintenance of CAT5/6 cable, installation and maintenance of VoIP Phone and IP cameras, installation and maintenance of Ethernet devices, installation and maintenance of CCTV Security cameras, and overall IT and network management.
