Gedsffati HD08-B Carbon Monoxide Alarm

Got this Gedsffati carbon monoxide alarm still in the box. It's the HD08-B model and it does more than just CO levels—it also shows the temperature and humidity on the screen. Pretty handy little device to keep around for safety, especially if you have gas appliances. It's got a clear digital display so you can actually see the ppm levels instead of just waiting for a beep. Brand new, never used.
