Hi Ya'all; I tested a 500 ppm for someone last year and it checked out as 64 ppm with a yellow dye or food color in it. The LVDC process is limited to about 40 to 50 ppm but the T.E. is very bright which says large particles. 15 to 20 is all you will every need.
With the HVAC process where the arc is submerged in CO2 then one can make clear, very small particles up to 40 or 50 ppm. With 2 liters it runs about 5ppm per hour. There really is no benchmark test available. One must have a stable process and then get a lab reading. If you have keep notes then you can use a Hanna PWT to know that you are in the ball park.
