(1) dongguan weixingda electronic technology co., ltd?
The carbon monoxide alarm of Dongguan Weixingda Electronic Technology Co., Ltd. is an electronic product that uses sound, light, air pressure and other forms to remind or warn us that we should take some actions. Alarm is divided into mechanical alarm and electronic alarm.
(2) Nanjing Aiyi Technology Co., Ltd.
The carbon monoxide alarm of Nanjing Aiyi Technology Co., Ltd. converts the concentration of carbon monoxide gas in the air into an electrical signal through a carbon monoxide sensor, and the size of the electrical signal is related to the concentration of carbon monoxide.
(3) Shanghai Ruilin Automatic Control Equipment Co., Ltd.
The carbon monoxide alarms of Shanghai Ruilin Automatic Control Equipment Co., Ltd. are classified according to sensors, including semiconductor carbon monoxide alarms, electrochemical carbon monoxide alarms and infrared carbon monoxide detectors. In terms of measurement sensitivity, accuracy, stability and resistance to cross-gas interference, infrared carbon monoxide detector has the best performance.
(4) Guangzhou Aili Electronic Technology Co., Ltd
The carbon monoxide alarm of Guangzhou Aili Electronic Technology Co., Ltd. is a semiconductor carbon monoxide alarm, which uses a semiconductor carbon monoxide sensor as a sensitive element. When the temperature, humidity and even wind force change greatly, it is not good for its accurate measurement, and it is easily interfered by other gases, such as alcohol, nitrogen oxides, hydrogen, alkanes and other gases, which are easy to be misreported, but the price is cheap.
(5) Jinan Dingnuo Technology Co., Ltd.
The carbon monoxide alarm of Jinan Dingnuo Technology Co., Ltd. is an electrochemical carbon monoxide alarm. Using zero-power electrochemical carbon monoxide sensor as sensitive element, redox electrochemical reaction was carried out by potentiostatic electrolysis. The concentration of carbon monoxide gas can be obtained by detecting diffusion current, which has good linear measurement range, high selectivity and strong anti-cross gas interference ability.
