This is a picture of the new test kit. You have a new meter to learn to read. It didn't work very well, but I only had 10 minutes training. IThe readout of the conductivity numbers changed the longer I held it. You have to rinse the meter's syringe with bleach (one of the containers) then with water (another container) then test the conductivity with a standard fluid ( another bottle) and then rinse and then test the 4th bottle with a standard buffered solution to test the ph. Then rinse, AGAIN. Then test the water in a cup you have poured from the blue line. Also, this makes you open the blue line up every day you do a treatment, increasing your chances of contamination. Also, the reading can be off .4 either way.
Bill, all I have learned is that is stems from Medicare requirements.
