American Made Carbon Monoxide (CO) Alarms and Sensors: Superior Technology Tested Most Reliable

Quantum manufactures all its carbon monoxide sensors in San Diego, CA.  We are located at 6827 Nancy Ridge Drive in San Diego, CA 92121. Quantum manufactures carbon monoxide (CO) alarms, carbon monoxide (CO) controls and carbon monoxide (CO) detectors in the USA.  Quantum also manufactures some components and products outside the USA. Quantum prefers to make its carbon monoxide (CO) alarm, control and detector products in the USA.  That is why we use Microchip Technology’s American made silicon, which is the heart of the  microprocessors in our products as well as our biotech carbon monoxide (CO) sensors, which are made in AMERICA.  If you want to support more American Made products buy from Quantum, we are the only carbon monoxide home and RV alarm manufacturer making its sensors in the USA. Buy the best buy American products.

Dr. Mark Goldstein. Quantum Group's CEO and founder, also the co-inventor of biotechnology based carbon monoxide (CO) sensor. This carbon monoxide alarm technology has been tested by the United States of America Department of Energy’s lead laboratory on indoor air quality to be the most reliable and the only False Alarm Free carbon monoxide alarm technology by Lawrence Berkeley National Laboratory (LBNL).  Please see LBNL Report 40556 (Click here).  Dr. Goldstein is also the founder of Carbon Monoxide Safety & Health Association (COSHA), which was instrumental in creating the market for carbon monoxide alarms and carbon monoxide detectors.  Dr. Goldstein was the most important pioneer in carbon monoxide (CO) alarm and carbon monoxide (CO) detector safety as he proposed the first state legislation and municipal ordinance while heading COSHA in 1987-1997.

Sensor substrate fabrication manager is chemist Alonso Castro.  He is shown running quality control instruments at Quantum Group Inc in the San Diego, CA factory.  He has worked for Quantum for more than 20 years 

Quantum sensor testing is shown in the San Diego, CA USA factory.  Each sensor is tested three times in carbon monoxide before it ships.  First it is tested as a raw sensor in carbon monoxide.  Next it is assembled into the sensor housing and tested again by computer.  Then it is assembled in a carbon monoxide (CO) alarm, carbon monoxide (CO) detector, carbon monoxide (CO) control or other carbon monoxide life safety device such as a Quantum Eye, which is a carbon monoxide visual detector.

Quantum Eye sensor production is shown in the San Diego, CA USA factory.  This device changes color from yellow – orange to green and the dark blue.  Green indicate caution and blue indicates danger and a need to evacuate.
