Fluke FLUKE-107 Esp Digital Multimeter 600V Cat Iii

Product Description

The FLUKE FLUKE-107 ESP is a CAT III-rated digital multimeter designed for general electrical diagnostics and trade fieldwork. Rated to 600 volts DC and capable of measuring resistance up to 40 megohms, it handles a broad range of electrical measurements in a compact form factor. At 0.4 pounds and measuring 5.7 x 2.9 x 1.1 inches, it fits easily in a tool bag or chest pocket. Electricians, HVAC technicians, and industrial maintenance techs rely on instruments in this class for fast, reliable readings on circuits, components, and wiring systems. The unit also measures capacitance up to 1000 microfarads and includes a diode test function, making it useful beyond basic voltage checks.

The FLUKE-107 ESP is suited for residential, light commercial, and industrial electrical work operating within CAT III environments. Typical applications include troubleshooting branch circuits, testing motor windings, checking capacitors on HVAC equipment, and verifying resistance across heating elements or control circuits. Its measurement range covers the common values encountered in 120-volt and 240-volt single-phase systems as well as low-voltage control wiring. Technicians working on HVAC controls, electrical panels, or motor circuits will find the combination of voltage, resistance, capacitance, and diode test functions practical for a single carry-along meter.

Key Features

• CAT III safety rating for use on distribution-level circuits up to 600 volts DC
• Measures resistance up to 40 megohms (40,000,000 ohms) for insulation and component checks
• Capacitance measurement up to 1000 microfarads, useful for HVAC run and start capacitor testing
• Built-in diode test function for semiconductor and circuit diagnostics
• Compact and lightweight at 0.4 pounds, sized for easy one-hand use in the field

Compatibility

Designed as a general-purpose digital multimeter for use in CAT III electrical environments. Compatible with standard test lead accessories appropriate for CAT III-rated instruments.

Installation Notes

This meter is a test and measurement instrument, not an installed component. De-energize and lock out circuits before connecting test leads whenever safe isolation is possible, following NFPA 70E arc flash and electrical safety work practices. Always confirm the meter's CAT rating is appropriate for the circuit being tested before taking measurements. Inspect test leads for damage before each use and replace any leads that show cracked insulation or worn probe tips.
