People who use alternative medicine learn about the healing properties of colloidal silver and see it as a way to improve their health. Colloidal silver generated with home generators can produce varying strengths of ionised silver measured in parts per million or PPM. While you have options in measuring the potency of your colloidal silver, you should know that home methods of testing are less than exact. Laboratory methods provide a little better accuracy, but samples from the same batch sent to different labs often measure different levels according to SilverMedicine.org.
Insert a TDS (total dissolved solids) or PWT (pure water test) meter into the distilled water you will use to generate your colloidal silver up to the designated maximum level line. To properly produce quality colloidal silver, the meter should read no higher than .2 ppm. Ideally, the meter should read 0 ppm. (If you are unsure of the accuracy of your meter, use the test solution sold by the manufacturer to calibrate or recalibrate your meter according to the manufacturer's instructions.) Clean your container, add fresh distilled water and retest if the reading is too high. Write down your beginning ppm level for comparison at the end of the process.
Turn on your generator and begin your electrolysis process. Do not add salt to the water to increase conductivity. This will skew your measurements at the end of the process.
Check your water with a laser pen every 30 minutes if using a low-power, battery-operated colloidal generator. Look for the Tyndale effect in the water as you shine the laser pen directly through the water. If microscopic particles of silver are present in the water, you will be able to see the laser beam in the water reflecting off the silver. Check the ppm levels on the TDS when you notice first faint presence of the Tyndale effect.
Continue your electrolysis process until your silver solution reaches the level you desire, using the same process as in Step 4. Check the water every 10 to 15 minutes once you detect the Tyndale effect because the conductivity of the water increases and the particles will accumulate more rapidly and may vary in size.

Allow the solution to stand for 60 minutes and retest to get a final reading.
Use room temperature distilled water to generate your colloidal silver. Do not add salt to your distilled water. Using a stirrer will increase the amount of silver you can suspend in the water.
