Re: CS>Measuring concentrations
The original term was the Mho. Yes, Ohm spelled backwards. In nineteen seventy one the unit was redesignated the Siemen in recognition of the work of Ernst Werner von Siemens. I always thought spelling Ohm backwards to indicate the reciprocal of the unit was a neat thing. No disrespect for Ernst intended. - Original Message - From: "Dan Nave" To: Sent: Saturday, November 10, 2007 1:48 PM Subject: Re: CS>Measuring concentrations Siemens in the unit used to designate "Electrical Conductance."

Re: CS>Measuring concentrations
" uS" is units of conductivity in Microsiemens per cubic centimeter as read by an "EC" meter [electrical conductivity ] That number just so happens to correspond very close to PPM up to around 30 uS...after..it has stopped dropping over time. Silver water loses some conductivity as it stabilizes. It's not actually measuring "PPM" silver, but hands you a useful number. A PPM/TDS meter works the same way, but fudges the conductivity number to correspond to PPM of Sodium Chloride salt in salt water*about* 1/2 the conductivity number...so, when using a PPM meter, double the reading.
