SAVIO Carbon monoxide sensor (CO) PW-920

Model: PW-920
EAN: 5901986046998

Product description

The Savio PW-920 sensor is designed to detect the presence of carbon monoxide from any combustion source. Thanks to regular tests for compliance with European requirements carried out at the GIG Research and Modeling Laboratories Group – Experimental Mine “Barbara”, we are sure that SAVIO sensors meet the stringent EU standards PN-EN 50291-1: 2018-06 and work perfectly.

  • PN-EN 50291-1: 2018-06 standard

The PW-920 carbon monoxide sensor meets the requirements of PN-EN 50291-1: 2018-06 in the following scope:

  • 50 ppm alarm within 60-90 minutes
  • 100 ppm alarm within 10-40 minutes
  • 300 ppm alarm within 3 minutes

Symptoms of carbon monoxide poisoning:

  • 50 ppm – maximum allowable concentration with constant exposure for 8 hours
  • 100-200 ppm – slight headache on exposure for 2-3 hours
  • 400 ppm – severe headache starting after about 1 hour of inhalation
  • 800 ppm – dizziness, vomiting and convulsions after 45 minutes of inhalation, coma after 2 hours
  • 1600 ppm – severe headache, vomiting, convulsions after 20 minutes, death after 2 hours
  • 3200 ppm – intense headache and vomiting after 5-10 minutes, death after 30 minutes
  • 6400 ppm – headache and vomiting after 1-2 minutes, death in less than 20 minutes
  • 12 800 ppm – loss of consciousness after 2-3 breaths, death after 3 min


Carbon monoxide is a particularly dangerous, colorless, tasteless and odorless, highly toxic gas. Researches proves the presence of carbon monoxide in the body impairs the blood’s ability to transport oxygen, which can lead to death. In closed spaces (homes, offices, camping vehicles, boats) even a small accumulation of carbon monoxide can be a danger.

Although many combustion products cause discomfort and can have a negative impact on health, carbon monoxide poses the greatest threat to human life.

Carbon monoxide is a product of incomplete combustion of fuels such as natural gas, propane, heating oil, kerosene, coal, charcoal, gasoline and wood.
