Riken Keiki GX-8000 Portable Multi Gas Detector
The Riken Keiki GX-8000 is a pump-operated portable multi gas detector designed for monitoring oxygen, combustible gases, carbon monoxide, and hydrogen sulphide in marine, offshore, industrial, and confined-space environments.
The Riken Keiki GX-8000 Portable Multi Gas Detector is a high-performance pump-operated multi-gas detector designed for continuous gas monitoring in hazardous industrial, marine, offshore, and confined-space environments. Capable of simultaneously monitoring up to five gas ranges, the GX-8000 detects oxygen, combustible gases, carbon monoxide, hydrogen sulphide, and high-concentration combustible gases (Vol%) depending on the selected sensor configuration. Its powerful sampling pump, rugged IP67-rated housing, intrinsically safe design, and large backlit LCD make it an ideal solution for demanding safety applications.
