Description
Product Overview
The Fluke iFlex 12 in Current Clamp (model 4637337) is engineered to provide high‑accuracy AC and DC current measurement with a flexible jaw that easily wraps around conductors of various sizes. Its compact dimensions of 7.09 x 5.91 x 3.94 inches and lightweight design at just 7.05 ounces make it ideal for handheld use in tight spaces, while the robust housing meets industrial durability standards for daily field work. The clamp features a true‑RMS sensor, delivering reliable readings even on non‑sinusoidal waveforms, and integrates seamlessly with Fluke’s handheld meters, allowing users to capture data quickly and accurately.
Each unit is supplied in a three‑pack configuration, providing a cost‑effective solution for teams that require multiple clamps for simultaneous testing or for organizations that need spares for rotation and maintenance. The packaging includes protective foam inserts and a clear instruction sheet, ensuring the clamps arrive in pristine condition and are ready for immediate deployment on the job site.
Constructed from high‑impact polymer and reinforced with metal reinforcement at stress points, the iFlex clamp offers long‑term resilience against drops, vibration, and exposure to typical workshop environments. The ergonomic handle is coated with a non‑slip rubberized material, reducing hand fatigue during extended measurement sessions and enhancing safety by preventing accidental slips.
Compatibility with Fluke’s extensive range of digital multimeters and data loggers expands the clamp’s utility across a variety of testing scenarios, from simple panel inspections to complex power quality analyses. The device’s intuitive interface, featuring a clear LCD display and simple push‑button controls, enables users of all skill levels to obtain accurate current readings with minimal training.

Usage
Designed for industrial electricians, maintenance technicians, and HVAC professionals, the iFlex 12 in Current Clamp excels in environments where quick, reliable current measurement is essential. Whether you are troubleshooting a motor overload, verifying the load on a circuit breaker, or performing routine preventive maintenance on a manufacturing line, the flexible jaws allow you to clamp around live conductors without disconnecting power, saving valuable time and reducing downtime.
In addition to traditional electrical testing, the clamp’s flexible design makes it suitable for use in confined spaces such as conduit bundles, cable trays, and equipment enclosures where rigid clamps would be impractical. Its true‑RMS capability ensures accurate readings on distorted waveforms commonly encountered in variable frequency drive (VFD) applications, renewable energy installations, and modern industrial automation systems.
The three‑pack offering is particularly advantageous for teams that need to monitor multiple circuits simultaneously, such as during load balancing assessments or when conducting comprehensive energy audits across a facility. By deploying multiple clamps, users can capture current data from several phases or circuits in parallel, improving the efficiency of data collection and analysis.
Furthermore, the iFlex clamp integrates with Fluke’s data logging software, enabling seamless transfer of measurement results to laptops or tablets for detailed reporting, trend analysis, and compliance documentation. This capability supports regulatory requirements for electrical safety inspections and helps organizations maintain accurate records of equipment performance over time.
