According to the Winsen MHZ19B datasheet, only 2000 and 5000 PPM models exist. (This was based on version of the datasheet. Version does list a 10000 PPM model.) The fake sensors may be suitable depending on what you use them for, but they show severe jitter of up to 50 PPM (peak to peak) and they often don''t properly do the ABC.
