Fluke 28 II Ex vs Chauvin Arnoux MTX 3297Ex: Which Intrinsically Safe Multimeter is Right for You?

Selecting the right intrinsically safe multimeter is essential for professionals working in hazardous environments. Two standout options in this category are the Fluke 28 II Ex and the Chauvin Arnoux MTX 3297Ex. While both are exceptional tools designed to meet demanding needs, each has unique strengths that cater to different preferences and requirements.

Let’s dive into a comparison to help you decide which multimeter is the best fit for your needs, highlighting their individual benefits without criticism.

Display and Resolution

  • Fluke 28 II Ex: Featuring a single display with up to 20,000 counts in high-resolution mode, this multimeter provides a straightforward interface for users who prefer simplicity. Its resolution is precise enough for most general applications, with 0.1 mV for voltage and 0.1 μA for current.

  • Chauvin Arnoux MTX 3297Ex: Equipped with a double display and a native resolution of 60,000 counts, the Chauvin Arnoux offers exceptional detail and clarity. It’s ideal for professionals who need the highest resolution, boasting 0.001 mV for voltage and 0.01 μA for current.

Measurement Features

  • Voltage and Current: Both models support up to 1,000 V for AC/DC voltage and 10 A for current. However, the Chauvin Arnoux excels with an optional clamp feature for current measurement and better resolution across the board.

  • Resistance: The Chauvin Arnoux measures up to 60 MΩ with finer resolution (0.01 Ω vs. Fluke’s 0.1 Ω), making it a better choice for applications requiring high precision.

  • Capacitance: If capacitance testing is a priority, the METRIX again takes the lead with a range of up to 60 mF, compared to Fluke’s 10 mF.

  • Temperature: The Fluke multimeter offers a broader temperature range (-200°C to +1,090°C), making it a top pick for professionals working in extreme environments. The METRIX covers a slightly narrower range (-200°C to +800°C).

  • Frequency: Both models handle frequency measurement well, but the METRIX supports a wider range of up to 200 kHz with better accuracy.

Additional Features

  • Fluke 28 II Ex: Renowned for its ruggedness, this multimeter is built to withstand the harshest conditions, ensuring reliability in extreme industrial environments. Its straightforward design makes it a user-friendly choice for general-purpose applications.

  • Chauvin Arnoux MTX 3297Ex: Designed with advanced users in mind, the METRIX includes features like dBm measurement, resistive power calculations, and communication capabilities via Optical/USB. This makes it ideal for professionals requiring detailed data analysis and connectivity.

Power Supply and Battery Life

  • Fluke 28 II Ex: Powered by 4 x AAA batteries, it provides up to 350 hours of battery life. While slightly less than the METRIX, this is sufficient for extended fieldwork.

  • Chauvin Arnoux MTX 3297Ex: Runs on 3 x AAA batteries with an impressive 400 hours of battery life, reducing the need for frequent replacements.

Build Quality and Safety

Both multimeters boast IP67 ratings, ensuring they’re dust-tight and waterproof. They’re rated for 1,000 V CAT III / 600 V CAT IV, making them safe for use in challenging environments. Additionally, both come with a 3-year warranty for peace of mind.

Which Multimeter Should You Choose?

The choice between the Fluke 28 II Ex and Chauvin Arnoux MTX 3297Ex depends on your specific needs:

  • Choose the Fluke 28 II Ex if you value ruggedness, reliability, and a broader temperature range. Its proven track record in extreme conditions and simplified interface make it a trusted companion for industrial professionals.

  • Opt for the Chauvin Arnoux MTX 3297Ex if you need high resolution, advanced features like communication and dBm measurement, or longer battery life. This multimeter is ideal for precision-focused tasks and detailed analysis.

Both the Fluke 28 II Ex and Chauvin Arnoux MTX 3297Ex are exceptional tools that meet the highest standards of safety and performance. These products are designed to ensure professionals have the right tools for success in hazardous environments.
