Notes

I wrote down the Salinity and Dissolved Oxygen readings I read off the meter, and transcribed them to the website. They have been highlighted on the website as errors, I may have put the decimal point in the wrong place, but I don't think so.

 

The EC readings on the meter were without any decimal point, ie 1704uS/cm, I put the decimal point to appease the website

 

Reply DM: that is the correct way to treat the EC readings - the water is quite fresh at the moment. I think the ppt and DO% were in the wrong columns on the datasheet. All readjusted now.
