Among the world’s smallest and lightest portable gas monitor Safety at your side Now evolved into a wearable device that weighs just Small, portable design for wear directly • At a mere 45 g, this small, portable design lets you to wear the device on your wrist, arm, or anywhere else — for example, on a helmet band. • In addition to buzzers and lamps, alarms are indicated by vibrations. Wear the device on your wrist or arm for immediate vibration alerts in the presence of danger, even in loud environments. Detection target gas: Oxygen (electrochemical type) Worn on arm (band type) Mounted to helmet band * Attached to belt clip Detection target gas: Hydrogen sulfide Incorporates durable new R sensor with advanced functions • The sensor’s superior durability and performance are backed by a three-year warranty (one year sensor warranty for GW-3 (O2)). • Usable across a wide range of temperatures (-20 °C to +60 °C). • We offer a lineup of carbon monoxide sensors almost entirely resistant to hydrogen interference. They’re ideal for use in environments like steel facilities where hydrogen is present. • We’re the first Japanese manufacturer to offer a lineup of dual carbon monoxide and oxygen sensors, bringing two-channel detection to the market in a compact and portable form factor. A safe design you can use anywhere • Protection level: Equivalent to IP66/68 (2 m, 1 h); designed to resist dust and water for confident use outdoors. • Intrinsically safe explosion-proof design (ATEX/IECEx/INMETRO Japan Ex) to allow use in hazardous locations. Detection target gas: Carbon monoxide *Attached to watch band Detection target gas: Oxygen (galvanic cell type) Attached to wrist (wristwatch type) Model GW-3 (C-) Detection target gas: Carbon monoxide (reduced hydrogen interference) Model GW-3 (CX) Detection target gas: Carbon monoxide and oxygen Name of gas Concentration display Time/data display Battery level Operating status Units The GW-3 (CX) can simultaneously display concentrations for both carbon monoxide and oxy
