The Fluke 1535 and 1537 2,500 V Insulation Resistance Testers are engineered to simplify frontline troubleshooting whether you’re on the factory floor or working in the field at a solar installation. With user selectable test voltages from 250 V to 2,500 V and resistance measurements up to 500 GΩ these testers allow you to cover more workload with a single tool. Equipped with an intuitive user interface, a short circuit current of up to 5 mA and a CAT IV 600 V rating these portable high-voltage insulation testers can deliver rapid and stable resistance measurements no matter where you take them. The 1537 Insulation Resistance Tester also allows you to store measurements for later review or PC transfer, using the provided software.
• Selectable Voltage Tests: Tailor your tests with user-selectable voltages of 250 V, 500 V, 1000 V, and 2500 V to cover both industrial and solar applications.
• Extended Insulation Resistance Measurement: Reach up to 500 GΩ in insulation resistance measurement for a thorough analysis.
• Intelligent Calculations: Automatically calculate Polarization Index (PI) and Dielectric Absorption Ratio (DAR), minimizing the influence of environmental factors.
• High Measurement Capacity: Execute up to 1,300 measurements at 2,500 V or 6,500 measurements at 250 V on a single charge, enhancing productivity.
• Enhanced Safety Features: Benefit from a CAT IV 600V rating and a built-in voltage alarm function for heightened safety during operations.
The Fluke 1537 has these additional features:
• Extended Measurements: The Fluke 1537 enhances your testing capabilities with AC/DC voltage and resistance measurements.
• Stable Resistance Measurements: Achieve faster, more stable insulation resistance measurements with a short circuit current up to 5mA.
• Fine-tunable Test Voltage: Adjust the test voltage from 250 V to 2500 V in 100 V increments to meet specific testing requirements.
• Dielectric Discharge Rate Calculation: Automatically calculate the dielectric discharge rate (DD) to aid in identifying elusive insulation issues.
• Ramp Test Mode: Linearly increase the applied test voltage 100 V/s to help identify potentially hard to identify fault conditions.
• Visual and Audio Continuity Indicator: Verify continuity visually on the screen display or with the audible indicator so you can focus on your testing procedure without looking at the display.
• Customizable Testing Parameters: Set user-defined labels, adjust test duration, and store measurement results for a tailored testing experience.
• Effortless Data Management: Download and manage data effortlessly with the provided PC software.
• Extended Warranty: Enjoy peace of mind with an extended 3-year warranty.

Fluke 750P31 Offers



Fluke 750P Series Pressure Modules are easy to use. To measure pressure, connect the pressure module to a pressure source or hand pump and then connect the pressure module cable to the calibrator. Apply pressure from the pressure source and it is displayed digitally on the calibrator. At the touch of a button, the pressure may be displayed in up to 11 different engineering units. When used with the 750 Series Documenting Process Calibrators, pressure readings can be date/time stamped and stored electronically for later retrieval. This saves time, eliminates errors, and supports F85compliance with quality standards and regulations.
