Product overview: Fluke 1550C FC 5 kV Digital Insulation Tester

Data collection from insulation tests made easy

The Fluke 1550C performs digital insulation testing up to 5 kV, and makes data collection easy through the Fluke Connect™ wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. It’s the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. And it comes with a three-year warranty and CAT IV 600 V safety rating.

Specifications: Fluke 1550C FC 5 kV Digital Insulation Tester

Electrical Specifications
The tester's accuracy is specified for one year after calibration at operating temperatures of 0°C to 35°C. For operating temperatures outside the range (-20°C to 0°C and 35°C to 50°C), add ± .25% per °C, except on the 20% bands add ± 1% per °C.
