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.

Key Features
• Quickly configure, start and stop tests remotely, a safe distance away from any operating, energized equipment, using Fluke Connect® and a smart phone
• Real time trending gives you easy-to-see visual cues
• Report creation using Fluke Connect desktop saves time and makes test results easier to understand
• Fluke Connect saves test results to the cloud for analysis and preventive maintenance

• Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected
• Continuous self-test so you always know it’s working
• Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC
• Audible/Silent mode for added convenience

Fluke’s two-pole voltage and continuity testers are built to work the way you work. They give you the best combination of safety, ease-of-use and fast answers available anywhere.
• Designed according to IEC EN 61243-3:2014 to verify the absence of voltage – even with discharged batteries.
• CAT IV 600 V, CAT III 690 V safety rating
• With 4 ways to indicate the presence of voltage – LED indicator, LCD display, audible tone or tactile feedback, always know if hazardous voltage is present (digital display on T130, T150, vibration indicator on T110, T130, T150)

• Save time by seeing voltage and current measurements at the same time
• Visual Continuity™ – the screen automatically turns green for continuity, perfect when it’s too loud to hear the beeper
• FieldSense™ technology for ac voltage, current and frequency, all without making electrical contact to live voltage
