Riken wristwatch type (wearable type) oxygen concentration meter GW-3(OX) GW-3(OX) 1 unit

Catalog number: GW-3(OX) Features: ●In addition to the buzzer and lamp, it also uses vibration to warn of gas, allowing you to quickly notice danger even in noisy environments. ●The world's smallest and lightest class, with a small and lightweight design of only 45g, so it can be worn on the wrist, arm, helmet band, etc. ●Can be used in a wide temperature range of -20 to 60°C. ●Can be used in a wide temperature range of -20 to 60°C. ●A lineup of carbon monoxide sensors (hydrogen interference reduction specifications) that are almost completely free of hydrogen interference (compatible with environments where hydrogen coexists, such as steel mills and iron and steel plants) ●Dustproof and waterproof construction ●Intrinsically safe explosion-proof construction ●Has the same performance as JIS-compliant products. (Except for JIS T 8201:2010 "6.10 Alarm Delay Test") Applications: ●To prevent oxygen deficiency and poisoning accidents at various work sites.
