Gaswatch GW-3 Series | GW-3 (CX) 

The GW-3 series is the smallest and most compact single-gas monitor from the Gaswatch series.

The newest lineup of the Model GW-3 (CX) series is lightweight, weighing just 45 grams. This allows you to wear the device on your wrist or arms for a hands-free method of gas monitoring for personal protection.

The GW-3 also incorporates durable new sensors with advanced functions with a three-year warranty*.

In particular, the CO sensors are almost entirely resistant to hydrogen interference, making them ideal for use in steel facilities and environments where hydrogen is present from carbon monoxide exposure. The dual sensor can simultaneously protect you from oxygen deficiency, carbon monoxide exposure.


The GW-3 series can be used in:
  • Refineries
  • Petrochemical facilities
  • Sewage treatment plants
  • Fire departments
  • Chemical plants
  • Tunnels
  • Mines
  • Hazardous waste sites
