Milwaukee Clamp Gun M12 Cordless Clamp Meter

The Milwaukee Clamp Gun M12 Cordless Clamp Meter, model number 2239-20NST, is a versatile and robust tool designed to meet the demands of commercial and industrial applications. From the moment I picked it up, I could tell that this tool was built to last, with a solid construction and an ergonomic design that makes it comfortable to use, even in challenging positions.

One of the standout features of the Clamp Gun is its ergonomic pistol grip design. This design not only makes it easier to hold for extended periods but also simplifies overhead measurements. The grip feels natural in the hand, reducing fatigue during prolonged use. However, I did notice that the location of the light switch could be improved. It's positioned in such a way that I often found myself accidentally triggering it, which can be a bit annoying when you're trying to focus on your measurements.

The 1.57-inch jaw opening is another notable feature. It accommodates large wire bundles with ease, making it suitable for a wide range of applications. Whether you're working on a commercial project or an industrial setup, the Clamp Gun can handle it. The true-RMS current measurement capability ensures accuracy and reliability, even in complex electrical environments. This is particularly important for professionals who need precise readings to diagnose and troubleshoot electrical issues.

One of the aspects that impressed me the most about the Clamp Gun is its bright and readable display. The high contrast white on black display is easy to read, even from a distance. This is a significant advantage when you're working in dimly lit areas or need to take quick glances at your readings. The display backlight further enhances visibility, ensuring that you can see your measurements clearly in any lighting condition.

The non-contact voltage detection feature is both convenient and safe. It allows you to detect the presence of voltage without making direct contact, which is a critical safety feature when working with high-voltage systems. The visual indication for non-contact voltage detection is straightforward and easy to interpret, providing an additional layer of safety.

The LED work light is a handy addition, especially when working in dark or confined spaces. It illuminates the area you're working on, making it easier to see what you're doing. However, as mentioned earlier, the placement of the light switch could be better to prevent accidental activation.

In terms of performance, the Clamp Gun doesn't disappoint. It has a wide current range of up to 1000 amps AC/DC and a voltage range of up to 1000 volts AC/DC. This makes it suitable for a variety of applications, from small-scale electrical work to large industrial projects. The frequency measurement capability, ranging from 6 Hz to 6 kHz, adds to its versatility, allowing you to measure a wide range of electrical signals.

One of the features that stood out to me was the in-surge function. This function allows you to measure the initial surge of current when a device is first turned on. It's fascinating to see the initial millisecond surge of current, which can often be double the continuous draw. While I may not have a practical use for this information in my day-to-day work, it's an interesting feature that showcases the advanced capabilities of the Clamp Gun.

The build quality of the Clamp Gun is excellent. It feels sturdy and well-constructed, with rugged overmolding that provides additional protection against drops and impacts. The tool is rated for CAT IV 600V and CAT III 1000V, indicating its suitability for use in high-voltage environments. This gives me confidence in its durability and reliability, even in demanding conditions.

The M12 REDLITHIUM rechargeable battery is another highlight. It provides long-lasting power, reducing the need for frequent recharges. The battery life is impressive, allowing me to use the tool for extended periods without worrying about it running out of power. The convenience of a rechargeable battery also means that I don't have to keep buying and replacing disposable batteries, which is both cost-effective and environmentally friendly.

In terms of functionality, the Clamp Gun offers continuity and capacitance measurements, adding to its versatility. The capacitance range of 0.1uF to 4000uF is sufficient for most applications, and the continuity function is reliable and easy to use. The hold function is another useful feature, allowing you to freeze the display reading for later reference.

Overall, the Milwaukee Clamp Gun M12 Cordless Clamp Meter is an impressive tool that combines accuracy, versatility, and durability. Its ergonomic design, bright display, and wide range of features make it a valuable addition to any professional's toolkit. While there are a few minor issues, such as the placement of the light switch, these are outweighed by the tool's numerous advantages.

I would highly recommend the Milwaukee Clamp Gun M12 to anyone in need of a reliable and versatile clamp meter. Its robust construction, accurate measurements, and wide range of features make it suitable for a variety of applications, from commercial electrical work to industrial projects. Whether you're a seasoned professional or a DIY enthusiast, this tool is sure to meet your needs and exceed your expectations.
