Portable Gas Detection Systems- P-508
The P-508 and P-510H Portable Gas Detectors are compact and lightweight combustible gas detection instruments designed for safe and reliable gas monitoring in industrial, marine, offshore, and hazardous environments. Manufactured by Tokaseiki Co., Ltd., these portable detectors feature automatic suction sampling, rapid response, audible alarm indication, and flameproof sensor construction for dependable field operation.
Description
The P-508 is designed for general combustible gas detection, while the P-510H is specifically engineered for hydrogen gas monitoring and is approved for hydrogen-related applications. Both models are suitable for outdoor use thanks to their drip-proof construction and intrinsically safe electrical design.
