The Professional Equipment Carbon Monoxide Gas Detector enables you to measure low levels of carbon monoxide in parts per million (PPM). It's intended to measure levels of CO gas in ambient air. An optional hand pump is available for this CO gas meter to allow ambient air samples from hard to reach places or from locations where air temperature is high.

• 3 1/2 digit LED display with back light option
• Data Hold feature - will stop reading carbon monoxide gas level and hold data until canceled
• Max Hold feature - will hold the maximum absolute value of carbon monoxide gas
• Soft carrying case and four AAA batteries

Safety Information for Carbon Monoxide Gas Levels

• 0-1 ppm - Normal background level
• 9 ppm - Maximum indoor air quality level
• 50 ppm - Maximum concentration for continuous exposure in any 8 hour average level
• 200 ppm - Mild headache, fatigue, nausea and dizziness
• 400 ppm - Frontal headache, life threatening after 3 hours
• 800 ppm - Death within 2 hours
• 1600 ppm - Nausea within 20 minutes, death within 1 hour
• 12800 ppm - Death within 1 to 3 minutes
