The Fluke 1555 and 1550C Insulation Resistance Testers are cracking tools for predictive maintenance on high-voltage equipment like switchgear, motors, generators, and cables. The 1550C tests up to 5 kV (0.25 MΩ to 1 TΩ), while the 1555 reaches 10 kV (2 TΩ), both with ±5% accuracy up to 100 GΩ and selectable voltages (50 V steps to 1000 V, 100 V above). Fluke Connect with the ir3000 FC Connector enables wireless data storage, real-time trending, and remote test control via the app, enhancing safety and efficiency. Features include capacitance (20 μF), leakage current (2 mA), ramp testing, and a 99-minute timer.
Safety is assured with CAT III 1000 V, CAT IV 600 V ratings, a >30 V live circuit warning, and a guard system to eliminate surface leakage. Weighing 3.6 kg, these IP40-rated testers use a 12 V rechargeable battery (750+ tests) and operate in -20 °C to 50 °C. The kit includes test cables, alligator clips, an IR adapter, AC cord, USB-IR cable, FlukeView Forms software, and a hard case (kits only), with heavy-duty clips for the 1555 and kits. Backed by a three-year warranty, the Fluke 1555 and 1550C are reliable, efficient mates for precise high-voltage insulation diagnostics.
