About This Product
Peace of mind near you. Evolves into a wearable device at only 45g
Features
■Small, lightweight design that can be worn directly
The compact and lightweight design weighs only 45g, so you can wear it anywhere, including your wrist, arm, or your helmet band. In addition to buzzers and lamps, gas alarms are notified by vibration. By wearing it on your wrist or arm, you can quickly notice danger through vibration even in noisy conditions.
■Equipped with a new high-performance and highly durable R sensor
Excellent durability and performance, with a 3-year sensor warranty (GW-3 (O2) only has a 1-year sensor warranty). Can be used in a wide temperature range (-20~+60℃). We have a lineup of carbon monoxide sensors that are virtually unaffected by hydrogen interference, and are compatible with environments where hydrogen coexists, such as in the steel market. The first carbon monoxide and oxygen dual sensor lineup from a domestic manufacturer, realizing two-component detection in a small and portable device.
■Safe design that can be used anywhere
Protection grade: IP66/68 equivalent, dustproof and waterproof construction for peace of mind for outdoor work. Intrinsically safe explosion-proof structure (domestic explosion-proof/ATEX/IECEx/INMETRO/China Ex), can be used in hazardous locations.
