Because it's an American site John you have to pay almost as much for P&P than you do the tester OK both together it's still a reasonable price but was just thinking if you need to return it and all that? Is there nothing similar on a UK site?

Hi John,
I use one of these for my marine setup.
I cant see why it wouldn't work for the pond.

I am probably wrong but.
If it says TDS meter then that's what it is, you can get one for £4. They sell them as being for salt testing.
salt will register as a dissolved solid, but the pond already has a tds reading without any salt. Tap water has a TDS reading.
The only way I see a TDS meter working is as a one off, reading before then after adding salt to calculate the difference. Then useless after that.
If I have this misunderstood I would be interested to know how a TDS meter could work for salinity??

It's in ppt so you have to remember to move the decimal point to turn that into a percentage.
It gives an instant reading of salt in parts per thousand and a temp check into the bargain.
There are similar ones for £20-30. On fleabay

Yes, instant reading, when its turned on goes through a few parameters of something then ready to go in around 5 seconds.
Because the pond was new put salt in the start of winter. Started with reduced water at 0.6% for a week or so,
then topped up water so salt then at 0.3%
Currently on 0.049%
Because it reads in ppt that is expressed as 0.49ppt, so you just need to remember that and move the decimal point.
So if you were doing a quick dip bath at say 2% salt that would read at 20ppt
A TDS would register the salt but also all the other trace elements in the water, so how would it distinguish what was salt??
