We’re excited to welcome INNO Instrument to the Cartoli lineup. Known for reliable fusion splicers, cleavers, OTDRs, and power analyzers, INNO brings trusted tools for fiber installation, testing, and maintenance.

The best HVAC techs don’t just clean, they verify. This guide covers five essential tools for ductwork and IAQ calls, including brush heads, long-run rotary brushes, inspection cameras, and airflow/pressure testing.

A simple identify, locate, inspect workflow can eliminate the most common variables in fiber troubleshooting—wrong strand selection, near-end faults, and connector contamination. Learn how fiber identifiers, VFLs, and end-face inspection kits work together as efficient first-pass checks before deeper testing.
