Questions about Ei Electronics Ei208D Carbon monoxide alarm

The device uses a permanently installed 3V lithium battery with a service life of at least 10 years. It is not intended to be replaced.

The audible alarm triggers with persistent CO concentrations according to these limits: 30 ppm: no alarm before 120 minutes; 50 ppm: between 60 and 90 minutes; 100 ppm: between 10 and 40 minutes; 300 ppm: within 3 minutes. A pre-alarm is activated above 43 ppm with the red light flashing; the higher the level and the exposure time, the faster the alarm.

The device displays a measured value on the integrated LCD display from a CO concentration of 10 ppm and checks the air every 4 seconds. An acoustic alarm and a red flashing LED are only triggered from a critical value of 43 ppm, whereby a pre-alarm function is also activated from this value. This means that the measured value can be constantly checked and is visible, not just from a critical value.

No, the detector can only measure the carbon monoxide content of the air.

According to the data sheet, this is a long-life lithium battery, which is permanently installed and has a service life of at least 10 years. -> https://www.eielectronics.de/kohlenmono...

Hi, I use it in a chalet, but I don't see why it couldn't be used in a camper van. If ever it is designed to work for 10 years if I remember correctly. After that you should not replace the battery as the sensor gets old and unreliable. Since it can save lives, I did not hesitate to buy it. A real pro detector costs a lot more and has to be tested periodically. Hopefully my comment will help.
