Greetings all you CS makers and users. Was reading the postings of Ringdance on Wed 1 Apr, and Fred on 2 Apr about their TDS-1 testers. Someone has passed on the idea that the TDS-1 is a conductivity measuring tool. Its *NOT* a conductivity tester. I also thought it was, until I ran some tests on it. Then I called Hanna Inst. Tech service to get the straight scoop on it. It measures IONIC CURRENT,only. If the fluid has a lot of particles in it and some are charged (ionic) and some are not, it will only read the charged ions. The TDS-1 probes are BOTH stainless steel and there fore will NOT produce an electric potential . The TDS-1 does NOT apply any electric potential to the probes. I have read the probes with a volt meter on the 4 micro volt scale and its reading zero. When the TDS-1 is placed into an ionic solution the emf (electromotive force) of the ions will cause a current to flow between the two probes which is measured and displayed as PPM of IONS. Reagents and other "calibration fluids" are really used to precipitate unwanted things out of the fluid. When I first recieved my TDS-1 I tested it in pure distilled water as reading 001ppm and then put the test fluid into storage for future testing of its (TDS-1) calibration. Since I go to great lengths to make sure nothing is in my CS , only pure H2O and single atoms of ionic silver, the TDS-1 will measure only the SINGLE ATOMS OF IONIC SILVER in my CS. I am going to make a posting on how I do this. This TDS-1 is probably more accuate than the lab tests you get with all their reagents etc. The TDS-1 *IS* a lab test instunment. An airplane pilot I know said "if you can`t trust your instruments your in trouble". Remember it reads IONIC CURRENT not conductivity. Now lets have some fun with it. Run some cold water from your kitchen faucet into a ceramic coffee mug. Read it--mine reads 233ppm. About normal for city water. Now dump it out and put in some warm water. read it--mine jumps up to 350ppm and the reading slowly drops as the fluid cools and the mug warms up .It will stabilize about 320ppm as the temperature equalizes between the water and the mug and everything is warm. Now dump it out and put in some real hot water from the faucet. read it--mine reads 460ppm and slowly drops as the temperature of the water and mug equalize, down about 327ppm , let it stand and cool awhile and it will keep dropping to the cold water reading or close to it, about 270ppm or so . Your reading will be not the same as mine since your city water is not the same as mine. Took some water from my "Brita" water filter. Reads 341ppm after going thru the ACTIVATED charcoal filter. It removes lead and copper by chemical action. They are poison to us. Also created a lot of ions by catalytic action. Not silver ions however. Went to a friends well out in the country and got a reading 006ppm from his water (It tasted good). Ions are CREATED by heating,by flow in METAL pipes ,by contaninates, by pollution of the water, by water heaters, BY electric current, by flames of burning, by radiation,by catalytic action etc.. All we want to do is measure the ionic current CAUSED by passing electricity thru pure water with silver electrodes and read it as PPM of IONS (silver ions) . That is what the TDS-1 does. The other day I opened up a new jug of distilled water and found it read 003ppm ,wondering if it was the water or the tester, got out my jar of calibration water (remember me putting that away at the beginning of this posting) I stuck the tester in it and it read 001ppm. Great ,now I know the tester is OK and the distilled water is not quite pure. I`ll just subtract the BASELINE 3 from my CS reading after makeing my CS, its real simple. Just be SURE you don`t get any thing in your CS except pure H2O and SINGLE ATOMS of IONIC SILVER. More on that soon.When my TDS-1 reads 20ppm in my CS I know its 20ppm of SINGLE SILVER ATOMS in the IONIC state. Thanks for taking the time to read this and keep on doing whats good for your selfs. Bless you all.
