Monitor December 2011 feature focus: New IR700 Gas Detector Protects Against Carbon Dioxide Leaks Offering reliable gas detection performance with low maintenance, our new, rugged Model IR700 Infrared Carbon Dioxide Point Detector requires no routine calibration and provides complete control room status and control capability for monitoring at the ppm level.
The Model IR700 features a precision IR point sensing element that provides reliable protection against the hazards of carbon dioxide gas leaks. The IR700 offers a true fail-to-safe design for dependable gas detection performance, heated optics to eliminate condensation and a dirty optics indicator informs the user the device must be cleaned before the lenses are entirely blocked, thereby reducing downtime.
Carbon dioxide is an inexpensive and versatile gas that is useful in diverse applications from beverage carbonation to enhanced oil recovery techniques. While nonflammable and fairly innocuous, leaks can be dangerous. Exposure to atmospheric concentrations above 5,000 ppm is considered unhealthy, making careful monitoring crucial at lower levels. Atmospheric concentrations at 1% v/v (10,000 ppm) will make some people feel drowsy while concentrations of 7% v/v and higher can lead to symptoms including dizziness, headache, visual and hearing dysfunction, and unconsciousness.
