  • 5 versions to choose from CO, H2S, O2, CO/O2, or H2 compensated CO
  • 3-year warranty (2 years for O2 sensor)
  • Over 4,000 hours of operation
  • Light and compact “watch type” design
  • Easily worn in your “breathing zone”
  • Watch band or clip-on options

·         The GasWatch 3 is the world’s smallest and lightest single-gas monitor. Weighing just 1.6 ounces, its compact form affords great comfort and flexibility in how you choose to wear it. It can be worn on your wrist as a watch, or clipped into your breathing zone on your lapel, hard hat or other safety equipment with its alligator clip.

·         The 5 different GasWatch 3 models can protect you from oxygen deficiency [GW-3(O2)], exposure to carbon monoxide [GW-3(CO)] or exposure to hydrogen sulfide [GW-3(H2S)]. A hydrogen compensated model [GW-3(C-)] can protect those who work in steel mills, refineries or other environments where hydrogen is present from carbon monoxide exposure. The dual sensor model [GW-3(CX)] can simultaneously protect you from oxygen deficiency and carbon monoxide exposure.

·         A small, field-replaceable, coin-type lithium-ion battery gives the GasWatch 3 over 4,000 hours of continuous operation. The hydrogen compensated CO can operate up to 2,500 hours, and the dual sensor CO/O2 model will get up to 2,000 hours of continuous operation.

·         The great battery life coupled with a 3-year warranty* gives the GasWatch 3 tremendous value and a low cost of ownership.
