Meters need to be calibrated frequently for the readings to mean anything. There are PH meters that are alright if you keep them calibrated but measuring chlorine levels is far more complex. There are some inexpensive ORP meters that will work for a little while before breaking, but they don't measure chlorine directly and tend to be tempermental at best and break quickly. Sensors that measure chlorine directly are very expensive, several thousand dollars, and are normally only sold for commercial pools.

Thanks for the input, exactly what I thought, and for the price of $7 or so, I figured they were junk
