M12 Clamp-Gun Clamp Meter for Accurate Readings
Tough enough to stand up to even the most demanding jobsite, the 2239-20 covers 100 percent of general testing applications and provides in-rush current measurement for motor starts to help prevent breaker trips. And thanks to its innovative pistol grip, the 2239-20 offers two key advantages over the competition: it orients its large, 1.57-inch jaws to take accurate measurements of up to 1,000-MCM cable, and it allows you to see the display even when clamped around a wire.Rated CAT IV 600V/CAT III 1,000V and featuring embedded non-contact voltage detection for safety, this clamp gun offers a current range to 1,000 amps AC/DC and a voltage range to 1,000. It also performs frequency measurements from 6 hertz to 6 kilohertz, resistance measurements to 600 kohms, capacitance measurements from 0.1 microfarad to 4,000 microfarads, and easily tests for continuity. 
The clamp gun has a current range to 1,000 amps AC/DC and a voltage range to 1,000. View larger. |
Equipped with a high-contrast, white-on-black display and a backlight for easy reading, this compact tool owes its comfort and durability to rugged over-molding. An added bonus, an LED work light provides ample illumination in even dark or enclosed areas.This kit includes a battery, charger, and carrying case. The 2239-20 runs on the same battery as other M12 tools, which means that any M12 battery or charger can be used to power the 2239-20. This tool is backed by a five-year limited manufacturer's warranty. 
Reliable, long-lasting LITHIUM-ION power is just one part of a full feature set. |
M12 Lithium-Ion Power: Compact, Lightweight, and Dependable
The 2239-20 owes its long-lasting, fade-free power to a 1.4-amp-hour lithium-ion battery. Since lithium-ion batteries are significantly smaller and lighter than competitive NiCad batteries, they play an integral role in making the 2239-20 ergonomic, comfortable to use, and easy to maneuver while you work. Also, lithium-ion batteries offer long battery life and charge in 30 minutes with the M12 charger.
