this doesn't look like a salinity sensor or input hardware failure, if there was a short cut or lose connection the raise or fall of the values would be much higher

please check if the base value (the mS) is also having a strange behaviour

is the temp. measurement correct?

Temp keep in 24-25, the actual sg is around 1.026. Is there any issue on Adc 1 or 2 ?http://img.tapatalk.com/d/14/04/26/ana4udu3.jpg
