![]() The best for Home Inspectors is the Forensics Detectors FD-600-CO since it comes with a 4ft probe for easy sampling at heater vents / registers. There are many excellent carbon monoxide analyzers available for inspectors, plumbers and HVAC technicians to purchase. What is the Best Carbon Monoxide Analyzer for Inspectors? The relationship between the voltage and the ppm CO reading is accomplished via "calibration" where a known value of CO ppm gas is exposed to the sensor and transposed to its representative output voltage. When the sensors react with carbon monoxide, their output potential voltage increases as a linear function of carbon monoxide concentration and hence a quantitative carbon monoxide part per million representation can be displayed. They are particularly useful for finding carbon monoxide leaks, making them ideal for inspectors evaluating heaters for cracked heat exchangers.Ĭarbon monoxide analyzers function by monitoring the presence of carbon monoxide in the air. Most units are made using electrochemical sensors that are robust and allow analyzers to be sold less than $500. Analyzers are useful for both point probe sampling and continuous monitoring. Infants, the elderly, and those suffering from conditions such as chronic heart disease, anemia, and more are particularly vulnerable.Ī carbon monoxide analyzer is a gas detection tool used to measure the concentration of carbon monoxide gas present in a given environment. More than 4,000 are hospitalized from carbon monoxide poisoning each year. Statistically, more than 400 Americans die from carbon monoxide poisoning that is not caused by the presence of fires per year. The chemicals being burned off, including as carbon monoxide, sulfur dioxide, and nitrous oxide, could escape into your home if this component cracks, causing disease or, in extreme situations, death.Ĭarbon monoxide is a dangerous gas that is even fatal in some cases. In terms of house safety, a damaged heat exchanger is a major concern. ![]() Is Carbon Monoxide Dangerous from a Cracked Heat Exchanger? A properly operating furnace should not produce substantial amounts of carbon monoxide, but a damaged or leaking heat exchanger might be dangerous. ![]() When a heat exchanger fails, the exhaust gases, including carbon monoxide, might mix with the air in the house under certain situations. The heat exchanger might fail for a variety of reasons, including cracks caused by the metal's constant expansion and contraction as it heats and cools, or rust. The heat exchanger in a furnace is a metal component that transmits heat from the fuel being burned while preventing your home's air from mingling with the furnace exhaust. What is a Heat Exchanger and Why is it Important? The unit comes with a 4 ft probe so sampling air at high vents / registers is easy. CO in a heater air stream may indicate a cracked heat exchanger that would warrant further investigation for maximum occupant safety. Like heated air coming our of vents / registers from a HVAC system. The unit can quickly identify carbon monoxide in air streams.
