Compared to other companies' products, the GX-3R and GX-3R Pro are small and lightweight.
Therefore, it is a very easy-to-use product that does not get in the way of work.
Some workers think detectors come with a wide detection range. OSHA in U.S., though, defines the breathing zone as, “a hemisphere forward of the shoulders within a radius of approximately six to nine inches.”
Because the sensor was also developed in-house, the GX-3R and GX-3R Pro were designed with an intimate understanding of the sensor characteristics. This enabled us to succeed in developing a compact, high-performance sensor.
Tough construction against poisoning-and impact-resistant!
New electrochemical oxygen sensor,which improved the basic characteristics.
2-in-1 configuration enabled smaller detector!
Significantly reduce H₂ interference with a two-sensor structure!
Ultracompact & lightweight infrared sensor
Improved basic characteristics! Toxic gas sensors
GX-3R and GX-3R PRO mounted with the new R sensor series, which have dramatically improved the performance from the previous sensors.

More Details
The GX-3R Pro can communicate with smartphone and tablets via Blutooth. Allows alarm to be issued to remote location in real time to notify emergency situations using the dedicated RK Link app. Also allows the main unit's setting to be altered.
Download the free RK Link app from Google Play or Apple Store.
GX-3R Pro can be connected to various devices.
The following are examples of development based on requests from customers.
The TR-L1 is a converter that converts Bluetooth signals into LoRa signals. It was developed in response to a request from a Korean customer who wanted to use LoRa. The TR-L1 also has an additional GPS function, enabling the user's current location to be ascertained, in addition to GX-3R usage.
Please contact us for details.
* LoRa is capable of communicating over hundreds of meter in unobstructed outdoor conditions.
The GX-3R PRO, provided by our subsidiary RKI Instruments, can also be connected to the Guardhat Platform. Guardhat is a platform that detects, warns and prevents industrial accidents. The system collects information in conjunction with sensors such as gas detectors and radiation detectors used in the field, detects and warns of dangerous industrial incidents, and helps to prevent accidents.

[Gas meter] Demonstration: How Robust to Submersion 
Since our company was founded in 1939 under the umbrella conglomerate of RIKEN, our management philosophy has been to create safe working environments. Our science and technology research laboratories have developed industrial gas detection warning devices, specializing in monitoring harmful gases in the work environment, as well as for explosion prevention from combustible gases. Without compromise, we continue to challenge ourselves to be technological leaders, developing and manufacturing a wide range of industrial gas detection systems and monitors. From large-scale gas detecting alarm systems to small-sized personal gas monitors for safety protection; used in many industries including semiconductor and LCD plants, petroleum complexes, steelworks, various tankers, oil storage stations, underground gas facilities, and volcanoes.
The “RIKEN Gas Detector” utilizing the principle of light wave interference, was exhibited at the 1937 Paris World Exposition. Its subsequent use greatly contributed to the prevention of accidents in coal mines where many fatalities were prevalent at the time. On the 15th March 2019 we celebrated our 80th anniversary. Supported by our history and tradition we shall further improve long established technology, and continue to innovative. Developing reliable quality products in response to the diverse needs of industry.
Utilizing our established overseas network, you could purchase
our product and services all over the world.
