TDS & Salt meters
Posted: Mon Feb 22, 2010 1:35 am
Hi All
I've been thinking about getting a TDS meter (simple hand held type) and while researching what's available and the costs etc. I noticed that they work by measuring the electrical conductivity (EC) of the water. Presumably the method of measuring the EC in a TDS meter is exactly the same as the method used in a salt meter.
If this is correct, and both meters measure the same thing but just display the results in a different way (TDS meters in ppm and Salt meters in % salinity) am I right in thinking that I can use a salt meter (which I've already got) to measure my TDS just by converting the reading?
If so, am I right in thinking that a salinity reading of 0.03% is the equivalent of a TDS reading of 300ppm?
Would be nice to save some £££s if I can
Thanks in advance.
