Gas Detection Product Range

As leaders in sensor technology, we offer a diverse line of gas detection equipment, from personal, portable instruments to sophisticated continuous-monitoring fixed systems. The list of gases that we can detect is the most comprehensive in the industry. Many of these gases also offer multiple detection ranges.

At the heart of any gas detection instrument is the sensor. With over 70 years of sensor technology experience, Riken Keiki has the knowledge and capability to deliver the most advanced detection techniques and manufacture some of the highest-quality sensors in the world. Our gas monitors are built around these high-quality, long-lasting sensors and can detect a wider range of gases than any other manufacturer.

Our portable gas monitors are lightweight personal safety devices designed to detect specific hazardous gases in the environment and can be worn on the body or carried by hand. With a wide variety of detectable gases, there is an instrument tailored to suit different applications.
