GX-3R Pro – 5-gas detector

Multi-gas detector |

The GX-3R Pro is a portable 5-gas detector from Riken Keiki – the world’s smallest and lightest five-gas personal monitor. It simultaneously measures standard confined space gases such as combustible gases (LEL), oxygen (O₂), carbon monoxide (CO) and hydrogen sulfide (H₂S), with a fifth configurable channel for a toxic or IR gas depending on sensor choice. The GX-3R Pro features rugged construction, Bluetooth data connectivity and robust alarm systems for reliable safety monitoring.
