CuBLU brings professional copper cable testing within reach of more installers and field teams. Compact, rechargeable and easy to use, it combines wiremap testing, fault diagnosis, cable tracing, voltage detection and remote identification, with higher models adding length and resistance measurement, PoE detection, and UniBLU app-based documentation and reporting.
All three options perform wiremap testing, fault diagnosis, tone generation and voltage detection. CuBLU II adds Bluetooth connectivity and app-based documentation via the UniBLU app, plus cable length and resistance measurement. CuBLU III includes everything in CuBLU II plus PoE detection.
CuBLU has a rechargeable Li-Ion battery with up to 96 hours of battery life, charged via USB-C. This is significantly longer than most comparable testers in this category, which still rely on replaceable AA batteries.
CuBLU II and CuBLU III connect to the UniBLU app via Bluetooth. The app lets you save, label and export test results directly from the field. CuBLU (the base model) operates as a standalone tester without app connectivity.
CuBLU identifies six named fault types: open, short, miswire, crossover, split pair and multi-fault. Shield continuity is also tested across all models. Named fault types give technicians clearer answers than a simple pass/fail indication.
Yes, but only on CuBLU III. It identifies PoE class, type, voltage and active pair on live ports – allowing technicians to safely check powered network ports without disrupting connected devices such as cameras, access points or sensors.
Cable length and DC resistance measurement is available on CuBLU II and CuBLU III. This is useful for verifying cable run lengths during installation and for assessing suitability before PoE deployment. The base CuBLU model does not include this feature.
CuBLU has built-in voltage detection that warns you if a cable is carrying AC or DC voltage before you connect – with protection up to 60 VDC / 50 VAC. This is a safety feature to protect both the technician and the tester in live environments.
CuBLU supports up to 16 remote IDs, allowing a single technician to identify and label multiple cable runs from one end without needing a second person at the far end.
Yes. CuBLU has a built-in tone generator with selectable frequencies from 800 Hz to 1500 Hz, including alternating-tone modes. Use it with a compatible audio-frequency inductive probe to trace and identify cables within a bundle.
CuBLU supports UTP, FTP and STP structured cabling (Cat 5e through Cat 8), as well as RJ11/12 telephone cables and coax using an adapter. It covers the full range of copper cable types found in typical structured cabling, AV, security and telephony installations.
Enhance your testing capabilities with our advanced OTDR test adapters. Designed to seamlessly integrate with both NSA and TestPro systems, these adapters are the perfect solution for accurate and reliable fiber optic testing.
