Insulation Testers
Safety and performance are two of the most critical requirements for any electrical system. Good quality insulation, a properly working grounding system and active protection assure the safety of people, electrical systems and buildings, and protect them against electrocution, fire and other equipment damage.
Fluke 1587 FC and 1577 Insulation Multimeters 
Two powerful tools in one.
The Fluke 1587 FC and 1577 Insulation Multimeters combine a digital 1 kV insulation tester with a full featured, true-RMS digital multimeter in a single compact, handheld unit, which provides maximum versatility for both troubleshooting and preventive maintenance. 
  • Insulation test (1587 FC: 0 01 MO to 2 GO) (1577: 0 1 MO to 600 MO)
  • Insulation test voltages (1587 FC: 50 V, 100 V, 250 V, 500 V, 1000 V), (1577: 500 V, 1000 V) for many applications
  • Live circuit detection prevents insulation test if voltage > 30 V is detected for added user protection
  • Auto-discharge of capacitive voltage for added user protection
  • Filter for motor drive measurements ( 1587 FC only)
  • AC/DC voltage, DC millivolts, AC/DC milliamps, resistance (0), and continuity

NEW
Fluke 1535 and 1537 Insulation Resistance Meter  
Periodically test insulation is mandatory to verify the integrity of coils and cables in motors, transformers, switchgears and electrical devices to keep safety of personal and assets. Fluke 1535 and Fluke 1537 could perform accurate and fast insulation test, also provide advanced functions like ramp voltage, polarity index, dielectric absorption ratio, and dielectric discharge (Fluke 1537) test, which help to effectively find defects such as partial or overall moisture and dirt, insulation breakdown and severe overheating and equipment aging.  
  • Ultra-large LCD display
  • A digitalized insulation test with an analog bar graph
  • Preset test voltage: 250 V, 500 V, 1000 V, 2500 V
  • Insulation measurement: 200 kΩ to 500 GΩ
  • Polarity index (PI)
  • Dielectric absorption ratio (DAR)
  • Automatic power-off after 10 minutes of inactivity
Fluke 1537 provides additional features as:
