Don’t expose yourself to Carbon Monoxide! Review the list below for the maximum allowable exposure limits and symptoms developed with CO inhalation. 9ppm: The maximum allowable concentration for short term 50ppm: The Federal OSHA standard for continuous exposure in any eight hour period. 200ppm*: Maximum concentration allowable any time according to OSHA. Slight headaches, fatigue, dizziness, nausea after 2-3 hours. 400ppm*: Frontal headaches within 1-2 hours, life threatening after 3 hours. Maximum allowable limit in flue gas according to EPA and AGA. 800ppm*: Headache, dizziness, nausea, and convulsions with 45 minutes. Unconsciousness within 2 hours. Death within 2-3 minutes. 1600ppm*: Headache, dizziness, and nausea within 20 minutes. 3200ppm*: Headache, dizziness, and nausea within 5-10 minutes. 6400ppm*: Headache, dizziness, and nausea within 1-2 minutes. 12800ppm*: Death within 1-3 minutes. * With exposure to this concentration and higher the effects can vary depending on size, age, sex, and health. |
The A771 is a CO adapter designed to work with your DMM to measure ambient air CO. Can also be used as a personal COalarm.
- Built-in alarm is preset to 30ppm. Setting can be set by user.
- Use with any DMM with minimum 2 1/2 digit LCD, 2 or 4Volt DC range and 10M Ohm or greater input impedance.
- Detect CO levels from 0-1999 ppm, with resolution as low as 0.1 ppm and ±5% of reading accuracy.
- Soft pouch included
