Battery-operated carbon monoxide sensor, 9V DC, electrochemical ORNO

The device is designed for continuous monitoring of the concentration of carbon monoxide (CO) in the air, detecting and alarming when the maximum safe concentration of this gas is exceeded.
The sensor does not detect other poisonous or flammable gases. The detector features: high quality electrochemical sensor, sound and visual notification, TEST button, which allows you to test if the sensor is working properly, low battery indication, LED signalization (red, green, yellow), indication of sensor malfunction and end of sensor life, carbon monoxide concentration measurement function in the range from 25 ppm to 999 ppm, compliance with the EN 50291 -1:2018 standard for home carbon monoxide detectors.
