Riken Keiki GX-3R vs. GX-3R Pro: Choosing your gas detector


When it comes to personal safety in environments where gas exposure is a risk, choosing the right gas detector is crucial. Riken Keiki, a leader in gas detection technology, has introduced two of the smallest and lightest personal gas detectors on the market: the GX-3R and the GX-3R Pro. Both models offer cutting-edge features designed to ensure your safety in potentially hazardous environments. But what sets them apart, and which one should you choose?

Riken Keiki GX-3R: the compact lifesaver

The GX-3R is touted as the smallest and lightest four-gas monitor in the world. It’s designed for seamless portability without compromising on performance. Suitable for a wide range of industries, from oil and gas to chemicals, this detector ensures you’re always aware of the presence of combustible gases, oxygen, carbon monoxide, and hydrogen sulfide.

Riken Keiki GX-3R Pro: advanced protection

Building on the success of the GX-3R, the GX-3R Pro adds enhanced features for even more robust gas detection. It retains the compact and lightweight design while introducing additional sensor capabilities, including the detection of various toxic gases (CO2, SO2, NH3, HCN, NO2 or PH3), making it ideal for more specialized applications.

Side by side comparison

Now, let’s compare these two models on key features:

  • Size and weight

Both models are celebrated for their compactness, making them easy to carry without fatigue. However, their dimensions and weight may differ slightly, with the GX-3R Pro potentially being marginally larger to accommodate additional sensors.

  • Gas detection capabilities

The primary difference between the two models lies in their gas detection capabilities. While the GX-3R focuses on the core four gases, the GX-3R Pro goes a step further by also detecting toxic gases, crucial for environments where toxic gases are present.

  • Battery life

Battery life is critical for ensuring that your gas detector is ready when you need it. Both models offer long battery lives, but specific usage times can vary based on the activated features and the frequency of alarms.

Which should you choose?

The decision between the GX-3R and GX-3R Pro ultimately depends on your specific safety needs and work environment. If you need a reliable, no-frills gas detector for common hazardous gases, the GX-3R offers excellent value and performance. However, if your work involves exposure to toxic gases or you require the most comprehensive gas detection available, the GX-3R Pro is the clear choice.

Both the Riken Keiki GX-3R and GX-3R Pro stand out as top choices for personal gas detection, offering a blend of performance, portability, and safety. If you need help choosing the right gas detector, you can always contact one of our specialists or check out the product video.
