$37.99. Carbon monoxide (CO) gas detector is fixed design to monitor the CO gas leak in range of 0 to 100/500/1000 ppm for 24 hours in the confined space or pipeline and gives sound and light alarm. Carbon Monoxide (CO) is measured in “Parts per Million” (PPM). The information below illustrates what symptoms may appear after one hour of exposure to CO: 0-9 ppm CO: no health risk; normal CO levels in air. 10-29 ppm CO: problems over long-term exposure; chronic problems such as headaches, nausea Se hela listan på firepros.com What is carbon monoxide (CO) and how is it produced? Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. It is produced by the incomplete burning of various fuels, including coal, wood, charcoal, oil, kerosene, propane, and natural gas.

World Health Organization (WHO) standards are published in mg/m3. For those who want to do the conversion, 1ppm = 1.145 mg/m3 and 1mg/m3 = 0.873 ppm. For those who don’t, remember that any level in mg/m3 is about 10% less when expressed in ppm. The Defender CA6150 Carbon Monoxide Alarm enables the user to read and monitor current CO levels as low as 10 PPM. read more : Questions? 1 (800) 221-4785 M-Th, 8am-4pm MST : CARBON MONOXIDE IS A SILENT KILLER.
