FLIR CM74 Pros/Cons and My Thought

The FLIR CM74 is a commercial-grade clamp meter that is designed for use by electricians and other professionals who need to measure AC and DC current, voltage, resistance, and continuity. It features a large LCD display, a built-in work light, and a variety of safety features.

Pros:

• The CM74 has a large, backlit LCD display that makes it easy to read readings in even low-light conditions.
• The built-in work light is a handy feature for illuminating work areas in dark or confined spaces.
• The CM74 has a variety of safety features, including a non-contact voltage indicator, a ground fault indicator, and a thermal overload protection.
• The CM74 is built to withstand the rigors of everyday use, with a durable rubber housing and a IP67 rating for dust and water resistance.

Cons:

• The CM74 does not measure DC voltage, which is a standard feature in most multimeters.
• The CM74 does not have a keeper for the test leads, which can make it inconvenient to store and transport.
• The CM74 does not come with a case, which is another common feature in multimeters in this price range.

User reviews:

Overall, the FLIR CM74 is a well-built and feature-rich clamp meter that is well-suited for professional use. However, the lack of DC voltage measurement and the absence of a case and test lead keeper are notable omissions for a multimeter in this price range.

My thoughts:

The FLIR CM74 is a good option for electricians and other professionals who need a reliable and accurate clamp meter for measuring AC current. However, the lack of DC voltage measurement and the absence of a case and test lead keeper are notable omissions for a multimeter in this price range. If you need a clamp meter that can measure DC voltage, you may want to consider a different model. However, if you only need to measure AC current, the FLIR CM74 is a good option.

Here are some alternative clamp meters that you may want to consider:

• Fluke 377 FC: This clamp meter has a wide range of features, including DC voltage measurement, a built-in work light, and a variety of safety features. It is also more expensive than the FLIR CM74.
• Klein Tools DT830B: This clamp meter is less expensive than the FLIR CM74 and does not have as many features. However, it does measure DC voltage and comes with a case and test lead keeper.
• Milwaukee 2890-20: This clamp meter is similar to the Klein Tools DT830B in terms of features and price. It also comes with a case and test lead keeper.

Ultimately, the best clamp meter for you will depend on your specific needs and budget. If you need a clamp meter that can measure DC voltage and comes with a case and test lead keeper, you may want to consider one of the alternative models listed above. However, if you only need to measure AC current and are on a budget, the FLIR CM74 is a good option.
