Hi, I have a couple of questions for Ted. I purchased a pH meter about a month ago and am slowly working my way to stabilising both urinary & salivary ph levels to around the 6.2 to 6.8 mark. Ted's advice has been most helpful in me achieving this. I am now looking to purchase both a Conductivity and ORP meter. In regard to the conductivity meter, I'm looking at one of two meters. One measures in millisiemens (range 0-19.99ms/cm) and the other in microsiemens (range 0-1999μs/cm). I'm not sure which one would be the most appropriate. As the measuring range on one of the meters only goes up to 1999μs/cm, I understand that you have to multiply the value by 10 to get the correct reading. i.e., a 450 reading on the meter equals 4500 microsiemens. Is this correct? I am also somewhat confused though on what the ideal conductivity reading should be. I have read where Ted has advised that the average urine conductivity is between 4200-4900 microsiemens and elsewhere where he has said that the ideal urinary conductivity should be around 15 millisimens. Correct me if I'm wrong but wouldn't 45000 microsiemens convert to 4.5 millisimens and 15 millisimens convert to 15000 microsiemens? In other words how does an average reading 4500 microsiemens equal 15 millisimens? Finally, I'm having trouble finding a supplier of Disodium EDTA. I live in Australia and have checked out a couple of chemical supplies with no luck. I know Ted does not like recommending anyone but is there anywhere I may source some locally?
