So, do y'all get the calibrating solution along with the meter? The saleperson asked if I wanted some ($7/200ml) and I got it. I assume it is a solution or colloid of known concentration which can be used to adjust the meter. I asked someone about using the meter to measure the PPM of CS and he said the thing to do was measure the solution with the meter and then send the CS off to be assayed. That way one could get a feel for the error of the instrument: For example, say you meaure 30ppm on your CS, send it off to be checked and it comes back 33ppm. Then you could assume that your meter reads 10% too low. I don't know if he knew about the calibrating solution, which seems a much better (and cheaper) method. They said they also sell the calibrating solution in a package of small one-use packets so they can be taken in the field, but these were about twice as much in price. turf -- The silver-list is a moderated forum for discussion of colloidal silver.
