i made 6 colliodal silver generators, and they all have different voltage outputs , and one of then has 1 milliamps output. they all have the constant current circuit to keep the current constant , the silver electrodes nearly 18 cm long are spaced 4cm apart or mm cant remeber. but the jars i use have plastic lids and i have them through that , i have no timer or any other circuit to turn them off after a certain time as it aint nessisary and even with the ppm meter , i allso use a digital multimeter and at certain ppm levels by the meter i allso measure the voltage levels to and without the ppm meter i can tell the ppm level by the final voltage output for that ppm level i brew for , i even have a 1.14 milliamps output cs generator to so the brewing time seems to be less, so i wont be waiting to long for it . and with all the notes ive taken with the size jar i use and the electrode length and spaceing and electrode submersion for a 500 mills amount of water to refill a 500 mills bottle , i can just monitor the voltage drops from the constant current circuit and when it tellys with the ppm ive had with the other brews which ive checked with the ppm meter , i then check it again and find they match . so if ya do ya brewing right and tests and home work and calculations then you can use the digital multimeter to determine ya ppm levels , by its voltage conductivity levels .
