RIKEN KEIKI GX-3R Pro – Advanced Portable Multi-Gas Detection
The RIKEN KEIKI GX-3R Pro is engineered for personnel who require reliable monitoring of potentially hazardous atmospheric conditions. Its compact design makes it suitable for carrying during inspection, maintenance, and operational activities.
Depending on the selected configuration, the detector can monitor combinations of combustible gases, oxygen, and toxic gases. The instrument provides real-time readings and alarm notifications to help users identify potentially dangerous atmospheric conditions.
Core Working Principle
The GX-3R Pro uses dedicated gas sensors to monitor the selected gases in the surrounding atmosphere. Sensor readings are processed by the instrument and displayed on its digital screen.
When a configured alarm threshold is reached, the detector activates its audible, visual, and vibration alarms to alert the wearer.
Depending on the model and configuration, the detector can monitor gases such as:
Combustible gases, including methane.
Oxygen (O₂).
Carbon monoxide (CO).
Hydrogen sulphide (H₂S).
Carbon dioxide (CO₂) or other supported gases, subject to the installed sensors.
The actual gases monitored depend on the instrument’s sensor combination. Confirm the required configuration before ordering.
